Abstract
A crystal resonator () includes: a piezoelectric resonator plate () on which a first excitation electrode and a second excitation electrode are formed; a first sealing member () that covers the first excitation electrode of the piezoelectric resonator plate (); and a second sealing member () that covers the second excitation electrode of the piezoelectric resonator plate (). The first sealing member () is bonded to the piezoelectric resonator plate () while the second sealing member () is bonded to the piezoelectric resonator plate () so that an internal space (), which hermetically seals a vibrating part including the first excitation electrode and the second excitation electrode of the piezoelectric resonator plate (), is formed. Plating films () are formed respectively on both the first sealing member () and the second sealing member (), on respective surfaces opposite to surfaces to be bonded to the piezoelectric resonator plate ().
