摘要
A tuning fork type crystal blank includes a base part, a pair of vibrating parts which extend from the base part parallel with each other, an auxiliary part including a support part located on one side of an alignment direction of the pair of vibrating parts relative to the base part and pair of vibrating parts and extending parallel with the pair of vibrating parts, and a holding part which is located on the opposite side to the pair of vibrating parts relative to the base part and connects the base part and the support part. When viewed in a planar view direction perpendicular to the alignment direction and to the direction in which the pair of vibrating parts extend, cut away part is formed in a side surface of the auxiliary part.
