METHOD OF MANUFACTURING PIEZOELECTRIC VIBRATOR, PIEZOELECTRIC VIBRATOR, OSCILLATOR, ELECTRONIC DEVICE, AND RADIO-CONTROLLED TIMEPIECE

摘要

A method of manufacturing a piezoelectric vibrator according to the invention is a method of manufacturing a piezoelectric vibrator in which a piezoelectric vibrating reed is sealed in a cavity formed between a base substrate and a lid substrate bonded to each other, the method including the steps of: inserting a core portion of a conductive rivet member, which includes a planar head portion and the core portion extending in a direction vertically to the surface of the head portion, into a penetration hole of the base substrate and bringing the head portion of the rivet member into contact with a first surface of the base substrate; attaching a laminate material having elastic properties to the first surface of the base substrate so as to cover the head portion; applying a paste-like glass frit on a second surface of the base substrate and filling the glass frit in the penetration hole; and baking and curing the glass frit.
