Abstract
A crystal oscillator () includes: a piezoelectric resonator plate () on which a first excitation electrode and a second excitation electrode are formed; a first sealing member () covering the first excitation electrode of the piezoelectric resonator plate (); a second sealing member () covering the second excitation electrode of the piezoelectric resonator plate (); and an internal space () formed by bonding the first sealing member () to the piezoelectric resonator plate () and by bonding the second sealing member () to the piezoelectric resonator plate (), so as to hermetically seal a vibrating part including the first excitation electrode and the second excitation electrode of the piezoelectric resonator plate (). An electrode pattern () including a mounting pad for wire bonding is formed on an outer surface (first main surface ()) of the first sealing member ().
