Abstract: A physical quantity measurement device includes a housing forming a measurement flow path through which the fluid flows and a container space that houses a part of a detection unit. An inner surface of the housing includes a housing intersecting surface that intersects an arrangement direction in which the measurement flow path and the container space are arranged, a housing flow path surface extending from the housing intersecting surface toward the measurement flow path, and a housing container surface extending from the housing intersecting surface toward the container space. The housing includes a housing partition that protrudes from the inner surface toward the detection unit and contacts the detection unit between the housing and the detection unit such that the housing partition separates the measurement flow path and the container space from each other.

Abstract: A sensor assembly includes a sensor chip, a circuit board, and a wire holding case. The wire holding case holds a bonding wire, which connects the sensor chip with the circuit board. The wire holding case is inserted in an insertion hole of a case. The wire holding case has a low rigidity portion and a high rigidity portion in an X direction. The low rigidity portion has a space accommodating the bonding wire. The high rigidity portion has a reference surface in contact with an inner periphery of the insertion hole to position the wire holding case in a Y direction. The high rigidity portion has a surface on the opposite side of the reference surface in the Y direction. The surface is biased from a projection, which is formed on the inner periphery of the insertion hole, in the Y direction.

Abstract: A physical quantity measurement device includes a housing forming a measurement flow path, a physical quantity sensor that detects a physical quantity of fluid in the measurement flow path, and a sensor support that supports the physical quantity sensor. The sensor support includes a support front surface on which the physical quantity sensor is disposed, and a support back surface behind the support front surface. The housing includes a floor surface facing a support end of the sensor support, a front wall surface facing the support front surface, and a back wall surface opposite to the front wall surface across the floor surface and facing the support back surface. A front distance between the physical quantity sensor and the front wall surface in a front-back direction is larger than a floor distance between the floor surface and the support end in a height direction orthogonal to the front-back direction.

Abstract: An air flow meter includes an inward part that is positioned inward of an intake pipe and an outward part that is positioned not inward but outward of the intake pipe. The air flow meter further includes a first detector provided in the inward part, and a second detector provided at a position closer to the outward part than the first detector.

Abstract: A physical quantity measurement device measures a physical quantity of a fluid. A detection unit has a physical quantity detector that detects a physical quantity of the fluid in a measurement flow channel. A housing accommodates at least a part of the detection unit and forms the measurement flow channel. The housing includes a housing attachment that is attached to a predetermined attaching target, and a position holder holding a position of the detection unit by contacting the detection unit. The housing includes an inward part positioned inward of the attaching target and an outward part positioned outward of the attaching target. The position holder is provided inward of the housing attachment in an alignment direction along which the inward part and the outward part are aligned.

Abstract: A sensor support portion supports a physical quantity sensor. A flow path housing portion forms a measurement flow path, which accommodates a support tip end portion of the sensor support portion. The sensor support portion includes a support front surface, which includes a front fixed portion away from the support tip end portion and fixed to an inner surface of the flow path housing portion. The physical quantity sensor includes a sensor exposure surface exposed from the support front surface. A separation distance between an end portion of the front fixed portion and an end portion of the sensor exposure surface is smaller than a separation distance between the end portion of the sensor exposure surface and the support tip end portion.

Abstract: A physical quantity measurement device includes a measurement channel through which the fluid flows to be measured, a physical quantity detector that detects a physical quantity of a fluid in the measurement channel, a housing forming the measurement channel, and a measurement outlet provided in the housing as a downstream end of the measurement channel. An outer peripheral surface of the housing includes an outer peripheral flat surface that extends in an arrangement direction along which an upstream end and a downstream end of the housing are arranged, and an outer peripheral inclined surface inclined with respect to the outer peripheral flat surface and provided between the upstream end and the outer peripheral flat surface in the arrangement direction. The measurement outlet is positioned upstream of the downstream end of the housing.
