Abstract
In a piezoelectric resonator device according to an embodiment, an internal space is formed by bonding a first sealing member to a crystal resonator plate and bonding a second sealing member to the crystal resonator plate. The internal space hermetically seals a vibrating part including a first excitation electrode and a second excitation electrode of the crystal resonator plate. Seal paths that hermetically seal the vibrating part of the crystal resonator plate are formed to have an annular shape in plan view. A plurality of external electrode terminals is formed on a second main surface of the second sealing member to be electrically connected to an external circuit board. The external electrode terminals are respectively disposed on and along an external frame part surrounding the internal space in plan view.
