ABSTRACT:
An insert terminal containing case includes a bottom wall, four side walls, and an opening at the upper portion, wherein a terminal made of a metal plate is vertically fixed to at least one of the four side walls by insert molding. A groove is vertically arranged at the outer side surface of the side wall fixing the terminal, the groove extending downward, the outer side surface of the terminal is partially exposed at the groove, and the inner side surface opposite the outer side surface of the terminal exposed at the groove is partially exposed at the inner side surface of the side wall. Therefore, when the terminal is provided in the case by insert molding, molding can be performed only using upper and lower dies. Furthermore, the terminal can be reliably exposed at the inner surface of the side wall. The insert terminal containing case has the minimum difference between the opening dimension of the case and the dimension of a piezoelectric diaphragm and is molded without using a sliding die.
