    摘要： Provided is a gas flow sensor that includes a heat-sensitive element for measurement disposed inside a duct through which a gas to be measured flows and a support mechanism for supporting the heat-sensitive element for measurement inside the duct. The heat-sensitive element for measurement includes an insulating film; a thin film thermistor portion formed on the surface of the insulating film with a thermistor material; a pair of comb electrodes which have a plurality of comb portions and are pattern-formed on the thin film thermistor portion using a metal so as to face each other; and a pair of pattern electrodes which are pattern-formed on the surface of the insulating film and are connected to the pair of comb electrodes. The support mechanism is disposed such that the planar direction of the insulating film is parallel to the direction of gas flow in the duct.

    摘要： In order to provide a thermal flow meter capable of preventing adherence of contaminants to an air flow sensing portion, the thermal flow meter (300) of the invention includes a bypass passage for flowing a measurement target gas (30) received from a main passage (124) and an air flow sensing portion (602) for measuring a flow rate of the measurement target gas (30) by performing heat transfer with the measurement target gas (30) flowing through the bypass passage through a heat transfer surface (437). The air flow sensing portion (602) is provided to be exposed to an exposed surface (402) arranged along a flow direction of the measurement target gas (30) inside the bypass passage is embedded, the mount support surface (402) has a stage (407) formed to surround a periphery of the air flow sensing portion (602), and an inner portion surrounded by the stage protrudes more than an outer portion of the stage.
