摘要： A piezoelectric vibrator has an airtight terminal comprised of a lead terminal and a piezoelectric member. The lead terminal has an inner lead portion and an outer lead portion. The piezoelectric member has an exciting electrode and a mount electrode disposed on a surface of the piezoelectric member. A plasma arc electrode is connected to a power supply for generating a plasma arc discharge. To bond together the inner lead portion of the lead terminal to the mount electrode of the piezoelectric member, the outer lead portion is connected to an output terminal of the power supply and the plasma arc electrode is positioned at a vicinity of a bonding portion for bonding together the inner lead portion and the mount electrode. A voltage is applied between the inner lead portion and the plasma arc electrode to generate a plasma arc discharge. The generated plasma arc is discharged to the bonding portion while subjecting at least the bonding portion to an argon gas atmosphere to thereby bond together with a solder the inner lead portion and the mount electrode.
