Highly stable piezoelectric oscillator, manufacturing method thereof, piezoelectric resonator storage case, and heat source unit

摘要

A piezoelectric resonator storage case, includes a piezoelectric resonator stored therein, and a resonator container for storing a metal case. Here, the piezoelectric resonator includes: a piezoelectric resonator body having the metal case and a piezoelectric resonator element which is sealed in the metal case in an air tight manner; and two lead terminals protruding from a bottom of the piezoelectric resonator body.
