An oscillator has a pair of upper and lower casing members in the form of plates, and a vibration plate pinched between the upper and lower casing members. A tongue-like vibrating portion is formed by forming a slit in the vibration plate inside an outer peripheral portion of the vibration plate pinched between the upper and lower casing members. Electrodes are formed on obverse and reverse surfaces of the vibrating portion.
