Claims

[Scope of utility model registration request]

A detection element holder is provided that is inserted into an insertion hole extending across an intake air passage and has an intake air circulation hole aligned with the intake air passage, and the detection element holder is divided into two by a dividing plane passing through the intake air circulation hole. Consists of a pair of holder halves.1. A groove capable of receiving the lead terminal of the heat-sensitive resistance flow velocity detection element disposed in the intake air circulation hole is formed on the joint surface of at least one half of the holder, and the lead terminal fitted in the groove is formed. An intake air amount detection device that is sandwiched between a pair of holder halves.
