Patent ID: 8653899

Claim:
A piezoelectric vibrator, comprising: a base substrate; a lid substrate that is joined to the base substrate in a state in which the lid substrate faces the base substrate; a piezoelectric vibrating reed which is housed in a recessed portion formed between the base substrate and the lid substrate, and on which an excitation electrode is formed; external electrodes formed on an outer surface of the base substrate; electrode pattern that electrically connect the piezoelectric vibrating reed and the external electrode; wherein the external electrodes and the electrode patterns are provided corresponding to respective electrical polarities, the electrode patterns have mount electrode portion and routing electrode portion respectively, the routing electrode portion corresponding to one of the polarities and the routing electrode portion corresponding to the other of the polarities face each other on an inner surface side of the base substrate, and the routing electrode portion for capacitance adjustment that extends along the routing electrode portion corresponding to the one of the polarities is extended from the mounted portion corresponding to the other of the polarities such that routing electrode portion corresponding to the one of the polarities and the routing electrode portion corresponding to the other of the polarities face each other.
