Summary:To provide an airtight terminal and a piezoelectric vibrator having a strong rigidity of a lead despite a small-sized constitution, and provide a method of fabricating an airtight terminal constituting a lead penetrating inside of a stem by one piece and a piezoelectric vibrator with an excellent yield. A stem 11 filled with a filling member 13 is penetrated only with one piece of a lead 12 formed from a lead frame. As an electric terminal, a conductive lead 16 connected to the stem 11 is provided other than the lead 12. The lead 12 and the conductive lead 16 of an airtight terminal 10 constituted by the stem 11, the lead 12, the filling member 13, the conductive lead 16 are connected to a piezoelectric vibrating piece 20, further, the stem 11 is capped to a case 30 to thereby constitute a piezoelectric vibrator 1.
