In a piezoelectric vibrator in which a piezoelectric vibrating reed is mounted on a mounting portion installed on a surface of the base substrate in a cantilevered state and the piezoelectric vibrating reed is accommodated to be covered by a lid substrate, the resistance of a lead-out electrode for supplying a drive power to the piezoelectric vibrating reed is reduced, thereby preventing degradation of vibrating performance. A first lead-out electrode formed between a mounting portion of a base substrate and a first through-electrode is formed in a peripheral region so as not to overlap with first and second excitation electrodes formed on outer surfaces of a piezoelectric vibrating reed for driving, thereby reducing the resistance of the first lead-out electrode.
