摘要： Although flow detection accuracy deterioration due to a subject fluid inflow into a gap between a sensor device and an engaging portion is prevented by an underflow inhibitor, the underflow inhibitor overflow to a sensor device surface results in the subject fluid turbulence, causing a flow element output fluctuation risk. One solution is a configuration comprising a sensor device made of a planar semiconductor material with a heating element and an intake air temperature detection element formed thereon, a support member containing an engaging portion the sensor device is engaged to, which is placed at a passage the subject fluid circulates and underflow inhibitor being filled into a void between the sensor device and the support member to prevent the subject fluid from flowing into the void, and a pooling portion being placed to prevent the under flow inhibitor from overflowing out of the void.

摘要： Projecting ends of terminal conductors projecting out of a thick portion of a holder and electrode terminals of a flow rate detecting element are electrically connected by bonding wires. A peripheral wall member is secured by an adhesive to a thin portion of the holder and the flow rate detecting element so as to surround the electrical connection portions between the projecting ends and the bonding wires and between the electrode terminals and the bonding wires. A gel is formed so as to seal the electrical connection portions, and a rubber is injected into and cured inside the peripheral wall member so as to seal the gel.

摘要： A heat-sensitive flow rate sensor employs a measuring resistor unit which has a heat-sensitive resistor. The resistance value of the heat-sensitive resistor progressively decreases towards a supporting portion by which the measuring resistor unit is supported in a detecting tube. Start-up time until the required operation temperature is reached after turning on of the power is shortened and high measuring accuracy is obtained.
