Abstract
In a flow rate sensor, a sensing passage, into which a fluid is introduced and in which a flow rate sensing element is disposed, a support member for supporting the sensing passage, and a circuit case, in which an electronic circuit unit for controlling the flow rate sensing element is accommodated, are formed integrally with each other, and the support member extends into a main passage through a hole opened to the main passage so as to position the sensing passage in the main passage. A structural member, the outside shape of which is formed to have a fluid resistance approximately similar to that of the portion of the support member extending from the hole, is disposed at a position approximately symmetrical with the portion of the support member extending from the hole about the sensing passage.
