Summary:Provided is a piezoelectric vibrator which is also compatible with the miniaturization thereof. In a piezoelectric vibrator where a piezoelectric vibrating piece is sealed in a cavity formed between a lid substrate and a base substrate made of a glass material, one through hole is formed in the base substrate, a pair of through electrodes are arranged in the through hole, the through hole is filled with a glass frit (6a) and the glass frit is solidified by baking so that the through hole is sealed by the glass fit. By arranging the pair of through electrodes in one through hole, one through hole is provided for one piezoelectric vibrator and hence, bending strength of the base substrate can be increased. Further, the piezoelectric vibrator is compatible with the miniaturization thereof.
