摘要
A tuning fork-type piezoelectric resonator plate has a resonator blank comprising a pair of vibrating leg portions and a base portion from which the leg portions protrude. The pair of leg portions are arranged in parallel protrudingly from one end face of the base portion, and a pronged portion is formed between the pair of leg portions in an intermediate position in a width direction of the one end face of the base portion. The base portion has a pair of through holes along the one end face of the base portion, and on another end face side opposite to the one end face of the base portion, a joining region that joins to an external portion. The pair of through holes are specially positioned and have special wall surface configurations.
