A piezoelectric resonator device in which excitation electrodes of a piezoelectric resonator plate are hermetically sealed, includes a plurality of sealing members that hermetically seal the excitation electrodes of the piezoelectric resonator plate. The plurality of sealing members each have a bonding layer, and at least one of the plurality of sealing members is provided with a bank portion and having the bonding layer formed on a top face of the bank portion. The plurality of sealing members are bonded together with the bonding layers of the sealing members, and a bonding material that contains an intermetallic compound is formed.
