Device for detecting physical quantity having a housing with a groove

摘要

A resistance heater 134 for detecting an air flow rate is supported by support members 134 A, 134 B. A housing 110 contains an electronic circuit 140 connected to the resistance heater 134 . The housing 110 is formed by integral molding with a terminal 142 for connecting the electronic circuit 140 to an external device. The terminal 142 is formed integrally with the housing 110 . The housing 110 has a groove 112 through which the terminal 142 is exposed in part.
