Abstract:
1. A flow rate measuring apparatus installed in a piping and inserted into an insertion hole formed in the piping, for measuring a flow rate of a fluid to be measured passing through the piping, the flow rate measuring apparatus comprising: a flow rate detection element for detecting the flow rate of the fluid to be measured; a circuit board provided on a side of the insertion hole with respect to the flow rate detection element, for driving the flow rate detection element; and a support member made of a resin, for supporting the circuit board and the flow rate detection element, the support member comprising a stepped portion formed between a region facing the circuit board and a region facing a detection portion of the flow rate detection element, wherein the support member comprises stress reducing means provided on a side opposite to the insertion hole with respect to the region facing the detection portion, for reducing stress applied to the flow rate detection element.
