PROBLEM TO BE SOLVED: To provide an airtight terminal that can support a piezoelectric vibrator with excellent shock resistance and to provide a small-sized piezoelectric vibrator. SOLUTION: In the airtight terminal having at least two metal-made leads 1, an insulation member 3 that positions and fixes the metal-made leads 1, and a metal-made cylindrical header 2 surrounding a circumferential part of the insulation member, a support member 7 whose one end is fixed by the insulation member 3 and whose other end is V-shaped or Y-shaped to support a piezoelectric vibration chip 4 is provided between the two metal-made leads 1 and the piezoelectric vibrator uses the airtight terminal.
