Abstract
A piezoelectric vibrator has a piezoelectric vibrating reed mounted on an upper layer base substrate through a conductive adhesive, in which the piezoelectric vibrating reed includes a first vibrating arm and a second vibrating arm extending along a first direction and arranged side by side in a second direction, a base supporting the first vibrating arm and the second vibrating arm and a first support arm and a second support arm positioned in the outer side of the first vibrating arm and the second vibrating arm in the second direction and bonded to the upper layer base substrate, in which an extrusion amount of the conductive adhesive in the inner side of the first support arm and the second support arm is smaller than an extrusion amount of the conductive adhesive in the outer side of the first support arm and the second support arm.
