PURPOSE:To stick a metalized surface excellent in sealing performance, which adheres at a low temperature, by separating a electrode lead part in a resonator and a metalizing part applied to sealing parts and electrically connecting the electrode lead part to the outside of the sealing part via through holes provided on a sealing member. CONSTITUTION:The inner sides of the dished sealing members 2 and 3 sandwiching both surfaces of the piezoelectric resonator l are metalized, and provided with the through holes 6 and 7 having lands on their openings. The lands on a surface on which the piezoelectric resonator 1 abuts and the lead part of the electrode 5 in the resonator 1 are heated, pressed and electrically connected. For sealing the piezoelectric resonator hermitically, it is isolated from the lead part of the electrode 5, the piezoelectric resonator 1 and the metalizing part 8 circularly provided on the outer periphery on the sealing member 5 are heated and pressed with pressure at the time when the through hole 6 is connected to the lead part of the electrode with indium. The Q of the resonator can be maintained as it is with out increasing the equivalent parallel capacity of the resonator.
