Abstract
A flow rate measuring apparatus can reduce flow rate detection errors resulting from a temperature difference between an inside and an outside of piping. A base has a base main body which is formed at its base end with a connector protruding to the outside of the piping, and a flange which is formed on the base main body and is fitted into an insertion hole in the piping. A plate made of PBT resin is arranged on the base, and a flow rate detection element is formed on the plate so as to be exposed therefrom. A circuit board is arranged at a side of the plate opposite to the connector. A housing has a fluid passage groove that cooperates with the plate to form a measuring passage in which the flow rate detection element is disposed, and an enclosure portion enclosing the circuit board. A cover closes the enclosure portion.
