Title:
共振装置及び共振装置製造方法
Document Type and Number:
Japanese Patent JP7194362
Kind Code:
B2
Abstract:
A resonator is provided that includes a vibrating section that vibrates in a contour vibration mode, a frame that surrounds at least a portion of the vibrating section, supporting sections extending along a Y-axis direction and connecting the vibrating section and the frame. The vibrating section includes a through hole that extends along an X-axis direction perpendicular to the Y-axis direction such that a coupling section is disposed between the through hole and each of the supporting sections. The length SL of the through hole in the X-axis direction is longer than the length Sd of the coupling section in the Y-axis direction.
