Abstract
A method of manufacturing a piezoelectric resonator unit that includes mounting a piezoelectric resonator on a base member using a conductive adhesive, keeping the piezoelectric resonator in an environment having a temperature and a humidity higher than those of a surrounding region for a predetermined time, performing frequency adjustment of the piezoelectric resonator by etching using an ion beam, and joining a lid member to the base member using a joining material such that the piezoelectric resonator is hermetically sealed between the lid member and the base member.
