Abstract:
A rectangular quartz crystal blank having long sides substantially parallel to a Z′ axis of the quartz crystal blank, and short sides substantially parallel to an X axis of the quartz crystal blank. The quartz crystal blank includes a center region, a second region and a third region that are adjacent to the center region along a long-side direction, and a fourth region and a fifth region that are adjacent to the first region along a short-side direction. A thickness of the second region and a thickness of the third region are smaller than a thickness of the first region, and/or a thickness of the fourth region and a thickness of the fifth region are smaller than a thickness of the first region, and 16.21≤W/T≤17.71, where W is a length of a short side and T is a thickness.

Claim (Index 1):
An AT-cut quartz crystal blank comprising:\n a quartz crystal body that is rectangular in shape in a direction normal to a main surface thereof, the quartz crystal body having a first region including a center of the main surface in the direction normal to the main surface, a second region and a third region that are adjacent to the first region on opposed sides thereof along a long-side direction in which long sides of the quartz crystal body extend, and a fourth region and a fifth region that are adjacent to the first region on opposed sides thereof along a short-side direction in which short sides of the quartz crystal body extend, wherein the long sides of the main surface are substantially parallel to a Z\u2032 axis of the quartz crystal blank, wherein the short sides of the main surface are substantially parallel to an X axis of the quartz crystal blank, wherein a frequency of a main vibration of the quartz crystal blank is in a range of 30.5 MHz to 37.0 MHz, wherein a thickness of the first region is substantially uniform, wherein at least one of (1) a thickness of the second region and a thickness of the third region are smaller than the thickness of the first region, and (2) a thickness of the fourth region and a thickness of the fifth region are smaller than the thickness of the first region, and wherein 16.21\u2264W/T\u226417.71, where W is a length of the first region, the fourth region, and the fifth region along the short-side direction, and T is the thickness of the first region.
