Abstract
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 stemfilled with a filling memberis penetrated only with one piece of a leadformed from a lead frame. As an electric terminal, a conductive leadconnected to the stemis provided other than the lead. The leadand the conductive leadof an airtight terminalconstituted by the stem, the lead, the filling member, the conductive leadare connected to a piezoelectric vibrating piece, further, the stemis capped to a caseto thereby constitute a piezoelectric vibrator
