Tuning fork-type vibrator
A tuning fork-type vibration piece is provided, in which a cushioning portion is formed on the base of a package to make contact with abutting portions of arm portions which are any parts but their edges, and the abutting portions of the arm portions allowed to contact the cushioning portion are electrodeless regions including no electrode, which prevents the risk of frequency fluctuations that may occur in case an electrode is chipped off by possible contact with the cushioning portion.
