摘要： It is an object to provide a method of adjusting a pressure sensor, in which adjustment of a diaphragm portion and adjustment of an amplification circuit connected to the diaphragm portion are simplified. A flexible circuit board having the amplification circuit mounted thereon is connected to a diaphragm member having the diaphragm portion formed with gauge resistances, and offset, span and temperature-compensating adjustment resistances, and adjustment of the adjustment resistances formed on the diaphragm member is performed in this state. The adjustment on the side of the diaphragm member including the amplification circuit accommodates adjustment deviation on the amplification circuit, and hence adjustment of the whole pressure sensor can be achieved by a single adjustment process. The adjustment process thus simplified can reduce manufacturing costs.
