Abstract:
1. An electronic timepiece comprises: a power-source voltage generating unit that converts external energy to electric energy and generates a power source voltage lower than a predetermined operating voltage; an oscillation-signal output unit that outputs an oscillation signal when the power source voltage generated is applied to the oscillation-signal output unit; a boosting unit that boosts up the power source voltage generated to at least the predetermined operating voltage; a boosting control unit that controls the boosting unit to boost up the power source voltage only for a predetermined time after the oscillation signal output unit starts to operate, based upon the oscillation signal; and a timing unit that times when the predetermined operating voltage boosted by the boosting control unit is applied to the timing unit.
