摘要： Technique of suppressing performance variations for each flow sensor is provided. In a flow sensor FS1 of the present invention, a part of a semiconductor chip CHP1 is configured to be covered with resin (MR) in a state in which a flow sensing unit (FDU) formed on a semiconductor chip CHP1 is exposed. Since an upper surface SUR(MR) of the resin (MR) is higher than an upper surface SUR(CHP) of the semiconductor chip (CHP1) by sealing the resin (MR) on a part of the upper surface SUR(CHP) of the semiconductor chip CHP1 in a direction parallel to an air flow direction, the air flow around the flow sensing unit (FDU) can be stabilized. Further, interface peeling between the semiconductor chip (CHP1) and the resin (MR) can be prevented by an increase of contact area between the semiconductor chip (CHP1) and the resin (MR).

摘要： An object of the invention is to provide a thermal air flowmeter which can reduce a detection error occurring during pulsating air flow due to a difference of response between rising and falling of detected flow or due to air flow dependence of response. A thermal air flowmeter 1 includes a heat-generating resistor 7 which heats liquid, a heating drive circuit 5 which causes current to flow in the heat-generating resistor 7 and thereby controls heating of the heat-generating resistor 7, and a temperature-sensitive resistor 9 which detects a temperature of the fluid heated by the heat-generating resistor 7. The thermal air flowmeter 1 detects a flow Q of the liquid based on the amount of heat of the liquid heated by the heat-generating resistor 7. Further included are: flow correction value calculating means 17 which calculates a flow correction value ca based on a variation dQ/dt of the detected flow Q and on a flow correction coefficient a set dependent on the detected flow Q; and flow correction means 18 which corrects the detected flow Q based on the flow correction value ca.
