Abstract
A built-in amplifier type combustion pressure sensor which can be assembled by simplified operation. A pressure detecting device is fixed to one end of a housing with leads extending inside the housing. The leads are bent in a predetermined form by inserting a spacer and a cover from an opening of the housing located on the opposite side of the pressure detecting device. An amplifier circuit board is inserted into the housing from the opening so that the leads are inserted into holes provided on the amplifier circuit board and protrude from the surface of the amplifier circuit board facing the opening side. The protruding end of each lead is connected to the amplifier circuit board.
