ABSTRACT:
A method is provided for producing a piezoelectric vibrator having an airtight terminal comprised of an annular stem, a lead disposed to pass through the stem and formed of a conductive material, and a filler for fixing the lead in the stem, and the piezoelectric vibrator having a vibrating piece connected to the lead of the airtight terminal and a case bonded to the airtight terminal to cover the vibrating piece. The method comprises an airtight terminal production process that produces the airtight terminal on a lead frame, and a piezoelectric vibrator assembly process that assembles the piezoelectric vibrator using the produced airtight terminal and on the same lead frame on which the airtight terminal is produced.
