Claims

[Scope of utility model registration request]

In an airtight terminal for holding a crystal vibrating piece between the leads and the wires, the lead wires are held as the lead wires in an airtight terminal in which a plurality of lead wires are mutually insulated and hermetically sealed inside a metal outer ring through glass. 2 out of 4 locations corresponding to both sides in the thickness direction and near both ends in the width direction of the crystal vibrating piece.
A long lead-out lead wire protruding to both the inside and outside of the glass is provided at one location, and a short holding lead wire is provided at the other two locations to protrude only to the inside of the glass. Airtight terminal for crystal resonator.
