Abstract:
The present invention has been made to improve measurement accuracy of a thermal flow meter. In the thermal flow meter according to the invention, a circuit package ( 400 ) that measures a flow rate is molded in a first resin molding process. In a second resin molding process, a housing ( 302 ) having an inlet trench ( 351 ), a bypass passage trench on frontside ( 332 ), an outlet trench ( 353 ), and the like are formed through resin molding, and an outer circumferential surface of the circuit package ( 400 ) produced in the first resin molding process is enveloped by a resin in the second resin molding process to fix the circuit package ( 400 ) to the housing ( 302 ).

Claim (Index 1):
A thermal flow meter comprising:\n a gas passage to take in and permit to flow therethrough of a measurement target gas flowing in a main passage, a circuit package having a flow rate measurement circuit to measure a flow rate by performing heat transfer between the measurement target gas flowing in the gas passage and the gas passage, a first resin sealing the flow rate measurement circuit, and a housing having an external connector for electrical connection to external devices, and housing the circuit package, formed by a second resin, a thermal expansion coefficient of which is different from a thermal expansion coefficient of the first resin, wherein the circuit package has a measurement terminal for outputting a measurement result of the flow rate measurement circuit, and an inspection terminal for inspecting the flow rate measurement circuit, after resin sealing, wherein the circuit package is in a shape having a plurality of sides, and wherein the inspection terminal and the measurement terminal are provided at different sides of the circuit package
