Abstract
Provide a highly efficient manufacturing method of a piezoelectric vibrator and to provide a piezoelectric vibrator manufactured by this manufacturing method. A method for manufacturing a piezoelectric vibratorincluding: a base boardand a lid boardwhich are superimposed on each other so as to form a cavity therebetween; a piezoelectric vibrating reedwhich is accommodated in the cavity and bonded to the base board; a bonding filmwhich is formed on the entire surface of the lid board on the opposite side to the base board so as to bond both boards to each other at a portion thereof being in contact with the base board, wherein the piezoelectric vibrating reed includes a pair of vibrating armsandand a weight metal filmformed on a tip end of each of the vibrating arms, wherein the bonding film is formed of a material which is capable of absorbing surrounding gas by being activated with laser irradiation, and wherein the method includes a laser irradiation step of simultaneously irradiating the weight metal film and the bonding film with a laser beam.
