Abstract
A piezoelectric vibrator including a base substrate and a lid substrate which are bonded to each other with a cavity formed therebetween; a piezoelectric vibrating reed which has a pair of vibration arm portions extending in parallel, a pair of excitation electrodes that vibrate the pair of vibration arm portions, and a mount electrode that is electrically connected to the pair of excitation electrodes, the piezoelectric vibrating reed being mounted on the base substrate within the cavity via the mount electrode; an insulation film which is formed on the piezoelectric vibrating reed so as to cover the excitation electrodes; and a getter material formed of the metallic material that is formed on any of the base substrate or the lid substrate so as to be arranged within the cavity and improve a degree of vacuum within the cavity by being heated.
