摘要：
A piezoelectric vibrator production method is disclosed, which can cope with a reduction in piezoelectric vibrator size and improve assembly accuracy and quality. The method of producing a piezoelectric vibrator having an airtight terminal composed 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, a vibrating piece connected to the lead, and a case bonded to the airtight terminal to cover the vibrating piece, the method comprising an airtight terminal production process for producing the airtight terminal, and a piezoelectric vibrator assembly process for assembling the piezoelectric vibrator using the airtight terminal, wherein in the airtight terminal production process and the piezoelectric vibrator assembly process, the airtight terminal is arranged and held on a same lead frame and is caused to flow consistently.
