Abstract

A thermal flow sensor has a housing through the inside of which a fluid is allowed to flow, and a supporting substrate disposed within and substantially in the center of the housing. A flat-plate shaped thermosensitive resistor and a fluid temperature sensor are provided on the supporting substrate. The thermosensitive resistor is disposed on the supporting substrate by being supported by a plurality of slender supporting members which support end portions of the resistor in such a manner as to provide narrow portions of a heat transferring path. The sensor detects flow rate with a good sensibility, while preventing any reduction in high levels of measuring sensibility and responsibility that are possessed by a small thermosensitive resistor.
