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).
