摘要： A resonator element includes a substrate having a first region performing thickness shear vibration, a second region located in a periphery of the first region and having a smaller thickness than the first region, a fixed end, and a free end opposite to the fixed end in the first region in a plan view. Excitation electrodes are disposed on a front and a rear of the first region and have regions overlapping each other in the plan view. A center of the first region and a center of the regions overlapping each other are located between a center of the substrate and the free end in the plan view. When Cs is a distance between the center of the regions overlapping each other and the center of the substrate in the plan view, a relation of 105 μm

摘要： A piezoelectric vibration piece has an inverted mesa-type structure, comprising a thinned portion serving as a vibration region at a central part of a piezoelectric plate; and a thickened portion formed all along or partly along perimeter of the thinned portion to reinforce the thinned portion. In the piezoelectric vibration piece, contact metals including a large number of discrete metallic thin films are provided on the whole surfaces of the piezoelectric plate. A piezoelectric vibration device comprises the piezoelectric vibration piece which is housed in a package, wherein extraction electrodes of the piezoelectric vibration piece are connected to internal terminals of the package through a conductive adhesive. These structural and technical advantages prevent undesirable flowage of the conductive adhesive before thermal curing. As a result, the piezoelectric vibration piece and the piezoelectric vibration device comprising the same successfully attain excellent vibration characteristics.

摘要： A piezoelectric vibrating piece includes a vibrating piece body and at least a pair of excitation electrodes. The vibrating piece body includes a vibrator. The pair of excitation electrodes are formed on respective front surface and back surface of the vibrator. The vibrating piece body is a twice rotated quartz-crystal vibrating piece cut out parallel to an X″-Z″ surface. The X″-Z″ surface is rotated around a Z-axis of a crystallographic axis of a crystal and further rotated around an X′-axis. The pair of excitation electrodes are collocated in a Z′″-axis direction determined by an X′″-axis. The X′″-axis is defined by counterclockwise rotation from a +X″-axis direction around a Y″-axis by 260° to 300°. The pair of excitation electrodes are disposed inclined with respect to the Y″-axis direction.
