发明名称 Method for manufacturing piezoelectric vibrator
摘要 Providing a method for manufacturing a package capable of suppressing occurrence of a discharge phenomenon during the anodic bonding and achieving stable anodic bonding of the base board and the bonding film. Providing a method for manufacturing a package including: an alignment step where an inner surface of the lid board 50 is superimposed onto an inner surface of the base board 40, and an outer surface of the base board 40 is disposed on an electrode base portion 70 for anodic bonding; and an anodic bonding step where a bonding voltage is applied between the bonding film 35 and the electrode base portion 70 while heating them to a bonding temperature, whereby the bonding film 35 and the base board 40 are anodically bonded, wherein the anodic bonding step involves applying the bonding voltage in a state where the penetration electrodes 32, 33 are exposed to a void portion 73 formed in the electrode base portion 70.
