description Provided is a piezoelectric vibrating device in which a first seal member (20) and a crystal vibrating plate (10) are joined, and a second seal member (30) and the crystal vibrating plate (10) are joined to provide an internal space (C1) in which a vibrating portion (11) of the crystal vibrating plate (10) including a first excitation electrode (111) and a second excitation electrode (112) is sealed in an air-tight manner. A seal path (115,116) sealing the vibrating portion (11) of the crystal vibrating plate (10) in an air-tight manner is formed in an annular shape in plan view. A plurality of external electrode terminals (32) for electrical connection to an external circuit board are formed on a second major surface (302) of the second seal member (30). The external electrode terminals (32) are disposed along an outer frame portion (W1) surrounding the internal space (C1) in plan view.
