Abstract
A tuning fork-type vibrator includes a tuning fork-type vibrating body including a base and legs. The tuning fork-type vibrating body includes two piezoelectric substrates, an intermediate electrode, surface electrodes and an entire-surface electrode that are laminated together. The surface electrodes are separated by separating portions extending from the base to each of the legs. The widths of the separating portions at a point of connection to the circuit board are wider than those of the separating portions at other points. The separating portions are formed by dividing an electrode provided on the entire surface of a piezoelectric substrate in the vibrating body with a dicer or by laser radiation or etching.
