Abstract
A method of manufacturing a piezoelectric vibrator according to the invention includes the steps of: inserting a core portion of a conductive rivet member, which includes a planar base portion and the core portion extending in a direction vertical to the surface of a base portion, into a penetration hole of the base substrate and bringing the base portion of the rivet member into contact with a first surface of the base substrate; applying a paste-like glass frit on a second surface of the base substrate and moving a first squeegee which comes into contact with the second surface with an attack angle in one direction to thereby fill the glass frit in the penetration hole; and moving a second squeegee which comes into contact with the second surface with an attack angle in a direction opposite to the one direction to thereby fill the glass frit applied redundantly on the second surface in the penetration hole.
