Beschreibung
Zusammenfassung:	In a piezoelectric resonator device of the present invention, an internal space (C1) is formed by bonding a first sealing member (20) to a crystal resonator plate (10) and bonding a second sealing member (30) to the crystal resonator plate (10). The internal space (C1) hermetically seals a vibrating part (11) including a first excitation electrode (111) and a second excitation electrode (112) of the crystal resonator plate (10). Seal paths (115, 116) that hermetically seal the vibrating part (11) of the crystal resonator plate (10) are formed to have an annular shape in plan view. A plurality of external electrode terminals (32) is formed on a second main surface (302) of the second sealing member (30) to be electrically connected to an external circuit board. The external electrode terminals (32) are respectively disposed on and along an external frame part (Wl) surrounding the internal space (C1) in plan view.
