Abstract: A sensor body contains a sensor element in a body recess opened at a body opening. A sensor substrate has a mounting surface on which a circuit element for processing a detection signal is mounted and holds the sensor body on the mounting surface. A sensor cover has a cover window penetrating between an intake passage and the body opening and covers the sensor body. A sensor filter is interposed between the sensor body and the sensor cover. A potting resin body is cured on the mounting surface so as to seal the circuit element. The sensor cover is embedded in the potting resin body on the outer peripheral side of the sensor body.

Abstract: An air flow rate measurement device disposed in an intake passage by passing through an insertion hole of an intake pipe of an engine to communicate inside and outside includes: a case having a bypass channel, a part of air flowing through the intake passage flows into the bypass channel; a flow rate sensor arranged inside of the case, and having a flow rate detector which detects a flow rate of air flowing through the bypass channel; and a humidity sensor arranged outside of the case, and having a humidity detector which detects a humidity of air flowing through the intake passage. A surface of the humidity detector is arranged to oppose a wall of the case through a clearance.

Abstract: A flow measuring device includes an output portion that outputs an electric signal having a shape of rectangle wave with an edge rising or falling in a signal value. The electric signal corresponds to a flow rate of intake air drawn into an internal-combustion engine. The output portion applies or stops a control voltage to a switching element disposed in an output wiring through which the electric signal is output so as to form the edge. The output portion has an edge relief part that changes the control voltage with progress of time so as to gradually increase or decrease the signal value at the edge.

Abstract: An oscillator circuit includes a resistor configured to control an oscillating frequency. The resistor includes a positive temperature coefficient resistor and a negative temperature coefficient resistor. The positive temperature coefficient resistor has a resistance, which increases in response to increase in temperature. The negative temperature coefficient resistor has a resistance, which decreases in response to increase in temperature.
