RESONATING ELEMENT, RESONATOR, ELECTRONIC DEVICE, ELECTRONIC APPARATUS, AND MOBILE OBJECT

摘要

A piezoelectric resonating element includes a piezoelectric substrate that includes a rectangular vibrating section and a thick section integrally formed with the vibrating section, excitation electrodes, and lead electrodes. The thick section includes a first thick section and a second thick section of which one end is formed continuous to the first thick section. The first thick section includes a first inclined section of which the thickness changes and a first thick section main body of a quadrangle column shape, and at least one slit is provided in the first thick section.

主权项

1. A resonating element comprising:
a substrate that includes:
a first area having a vibration area, which performs a thickness shear vibration vibrating in a vibration direction, anda second area, which is formed integrally with the first area, a thickness of the second area being larger than a thickness of the first area; the first area includes:
first and second outer edges that intersect the vibration direction and that are spaced apart from each other in the vibration direction; andthird and fourth outer edges that extend in the vibration direction and that are spaced apart from each other in a direction intersecting the vibration direction; the second area includes:
a first inclined section having first and second circumferential edges opposite to each other and having a thickness that increases from the first circumferential edge that comes into continuous contact with the first outer edge of the first area toward the second circumferential edge;a first thick section that comes into continuous contact with the second circumferential edge of the first inclined section;a second inclined section having third and fourth circumferential edges opposite to each other and having a thickness that increases the third circumferential edge that comes into continuous contact with the third outer edge of the first area toward the fourth circumferential edge; anda second thick section that comes into continuous contact with the fourth circumferential edge of the second inclined section, wherein the first thick section has amounting section that is fixed to a mounted member.
