<p>PROBLEM TO BE SOLVED: To provide a piezoelectric vibrator capable of improving adhesive strength between a pair of support arm parts and a mounting surface and suppressing deterioration in productivity.SOLUTION: The piezoelectric vibrator includes: a package including a base member and a lid member forming an air-tightly sealed cavity between the base member and the lid member; and a piezoelectric vibration piece stuck to a mounting surface of the base member and stored in the cavity. The piezoelectric vibration piece includes: a vibration part having a pair of vibration arm parts arranged alongside each other in a first direction; a base part for connecting both end parts of the pair of vibration arm parts; a support part having a pair of support arm parts arranged on both sides of the vibration part in the first direction; and a combination part for combining the base part to the support part. The piezoelectric vibration piece is fixed on the base member by respectively sticking the pair of support arm parts to the mounting surface by adhesive and a shape of the adhesive for respectively sticking the pair of support arm parts to the mounting surface is formed so that a second direction orthogonal to the first direction in the mounting surface is longer than the first direction.</p> |
