Abstract
A pressure detecting apparatus is composed of a first case insert-molded with connector pins, and a second case made of metal. The first case and the second case are assembled together to form a pressure detection chamber hermetically sealed with an O-shaped ring sandwiched between seal surfaces of the two cases. The first case is formed by using a molding die that has a gate for injecting resin approximately in parallel with a seal correspondence surface for forming the seal surface of the first case.
