摘要： A substrate includes a first surface portion, which covers a heat receiving portion of a radiation member together with a resinous member. The substrate further includes a second surface portion, which is on the outer periphery of the first surface portion. The substrate makes contact with the resinous member via the second surface portion. The first surface portion and the heat receiving portion have a first contact boundary therebetween. The second surface portion and the resinous member have a second contact boundary that surrounds the first contact boundary. The second contact boundary is sealed using a sealing member. The sealing member is restricted from flowing into a boundary between the first contact boundary and the second contact boundary.

摘要： A sensing unit is constructed of a heater element and a temperature sensing element. The sensing unit is arranged in a region, in which measurement air, which flows into the inflow passage through the bypass inlet, bends at the substantially right-angle and contracts in flow. Alternatively, the sensing unit is arranged in a region immediately after an area, in which the measurement air flowing through the bypass inlet bends at the substantially right-angle. The lengthwise directions of the heater element and the temperature sensing element are respectively arranged to be in parallel with both thickness-wise side faces of the measurement body. Thereby, even when a flow rate of measurement air changes, an influence due to the change can be restricted from being exerted. Therefore, the maximum flow rate can be measured within the lengthwise range of the heater element from a low flow rate to a high flow rate.

摘要： An airflow meter has a bypass passage disposed in an air passage and a sensing portion disposed in the bypass passage to detect an airflow amount. The bypass passage is provided with a restriction portion to gradually decrease a passage width of the bypass passage in an airflow direction in the bypass passage. The restriction portion includes a first restriction portion and the second restriction portion disposed at an immediately downstream side of a narrowest portion of the first restriction portion. The first restriction portion gradually decreases the passage width in the airflow direction. The second restriction portion increases the passage width than the passage width at the narrowest portion in a stepped manner. The sensing portion is located in a bound in which the restriction portion is disposed.

摘要： A flow measuring device includes a housing, a support, and a flow measurement element. The housing defines a passage therein and includes a passage narrowing part, which reduces a cross-sectional area of the passage, in a predetermined part of the passage. The support has a platy shape and is disposed along a flow direction of fluid flowing in the passage. The flow measurement element is located inside the passage narrowing part and is disposed on a surface of the support. The flow measurement element detects a flow rate of fluid flowing in the passage. The passage narrowing part has an inner wall surface that gradually reduces a width of the passage from a center side to both end sides of the passage in a height direction of the passage, which is perpendicular to a direction of the width of the passage.

摘要： A flow detecting device is provided to a fluid passage through which a main flow of fluid passes. A sensor body has a bypass passage through which a bypass flow passes from the main flow. The bypass passage has a bent portion, which is located midway through the bypass passage, and an outflow passage, which is located downstream of the bent portion. The flow direction of the bypass flow changes at the bent portion toward the outflow passage through the bypass passage. A heating element is arranged in the bypass passage. The heating element generates heat by being supplied with electricity for detecting a flow amount of fluid. The sensor body has a side surface defining an opening through which dynamic pressure caused by counterflow is released to an outside of the outflow passage when fluid causes counterflow in the fluid passage in a direction opposite to a flow direction of the main flow.
