A method of fabricating a case accommodating a piezoelectric vibrating piece therein in a piezoelectric oscillator including the piezoelectric vibrating piece, includes the steps of: applying deep drawing to a conductive plate member to shape the plate member in a nearly cylindrical shape with a bottom; pressing an inner surface of a bottom part of the plate member by a punch for step drawing while an outer surface of the bottom part is being abutted against a surface including an opening of a… CONTINUE READING
