Abstract
A piezoelectric vibration component that includes a sealed space formed between first and second package members, and a piezoelectric vibrator is bonded to the first package member with first and second conductive adhesive portions. In the piezoelectric vibrator, a first vibration electrode and a first extended electrode are formed on a first surface of a piezoelectric substrate, and a second vibration electrode and a second extended electrode are formed on a second surface of the piezoelectric substrate. At least the second extended electrode provided on the second principal surface has a higher bonding strength with respect to the conductive adhesive than that of the electrodes on the first principal surface. The electrode patterns on the first and second principal surfaces differ from each other so that the first surface and the second surface can be distinguished from each other.
