摘要： Provided is a flow rate measuring apparatus which prevents a reduction in flow-rate detection accuracy through reducing stress applied to a flow rate detection element. The flow rate measuring apparatus includes a support member (8) provided with a stepped portion (9) formed between a region facing a circuit board (5) and a region facing a detection portion of a flow rate detection element (3), in which the support member (8) includes a groove portion (11a) provided on a side opposite to an insertion hole (2) with respect to the region facing the detection portion, for reducing stress applied to the flow rate detection element (3).

摘要： Provided is a flow rate measuring apparatus which suppresses deformation of a base main body due to vibration of a pipe so as to be able to reduce occurrence of disconnection of wires due to the vibration of the pipe. The flow rate measuring apparatus includes a bonding portion (16) corresponding to a deformation suppression portion provided between an inner wall surface (17a) of a flange (17) of a base (11) and an outer circumferential wall surface (6a) of a cover (6) covering a circuit board (5), which is opposed to the inner wall surface (17a), for connecting the flange (17) and the cover (6) to suppress the deformation of a base main body (32) of the base (11) due to vibration of an intake pipe (50).
