Abstract
This invention prevents an adhesive portion between a piezoelectric element and a conducting member of a small vibrator from peeling off. In a vibrator, a conducting member includes at least one first adhesive portion adhered to an electrode, at least one second adhesive portion adhered to an elastic member, and a feed portion electrically connected to means for applying an external voltage. In the conducting member, a path length from the feed portion to the first adhesive portion is longer than a path length from the feed portion to the second adhesive portion.
