摘要： A third through hole is formed in a crystal resonator plate of a crystal resonator to penetrate between a first main surface and a second main surface. A through electrode of the third through hole is conducted to a first excitation electrode. A seventh through hole is formed in a first sealing member of the crystal resonator to penetrate between a first main surface and a second main surface. The through electrode of the third through hole is conducted to the through electrode of the seventh through hole. The third through hole is not superimposed to the seventh through hole in plan view.

摘要： In a crystal oscillator accordance to an embodiment, a crystal resonator plate is bonded to, via laminated bonding patterns, a first sealing member covering a first excitation electrode of the crystal resonator plate; and a second sealing member covering a second excitation electrode of the crystal resonator plate. An internal space is formed, which hermetically seals a vibrating part including the first and second excitation electrodes of the crystal resonator plate. The laminated bonding patterns include a laminated sealing pattern annularly formed to surround the vibrating part in plan view so as to hermetically seal the internal space, and a laminated conductive pattern establishing conduction between wiring and electrodes. The laminated conductive pattern is disposed within a closed space surrounded by the laminated sealing pattern. To the laminated sealing pattern, GND potential is applied when the crystal oscillator operates.

摘要： A piezoelectric resonator device having a sandwich structure is provided, which can avoid gas generation with reduced size or height. A crystal resonator includes a crystal resonator plate, a first sealing member and a second sealing member. A sealing-member-side first bonding pattern and a sealing-member-side second bonding pattern, both to be bonded to the crystal resonator plate, are formed respectively on the first and second sealing members. On the crystal resonator plate, a resonator-plate-side first bonding pattern to be bonded to the first sealing member is formed on a first main surface and a resonator-plate-side second bonding pattern to be bonded to the second sealing member is formed on a second main surface. The sealing-member-side first bonding pattern is bonded to the resonator-plate-side first bonding pattern, and the sealing-member-side second bonding pattern is bonded to the resonator-plate-side second bonding pattern, both by diffusion bonding.
