Abstract
A tuning fork-type vibration piece is provided, in which a cushioning portion is formed on the base of a package and allowed to contact parts for contact of arm portions which are any parts but their edges, and the parts for contact of the arm portions that contact the cushioning portion are electrodeless regions, which prevents the risk of frequency fluctuations caused by any electrode being chipped off by contact with the cushioning portion.
