The piezoelectric vibrating piece (20) comprises a base portion (29) having an adhesive area on a first surface of electrically conductive adhesive 31 for mounting, a pair of vibrating arms (21) extending in a first direction from one edge of the base portion, base electrodes (23a, 25a) arranged in the base portion, an exciting electrode (23c, 25c) extending in a first direction and connecting the base electrode to excite a pair of vibrating arms. The area where the base electrodes (23a, 25a) conduct the electrically conductive adhesive (31) is smaller than the adhesive area (33).
