Abstract

A piezoelectric transducer includes beam portions supported by a base portion at an end portion and extending in a direction away from the base portion above the base portion. Each beam portion includes a piezoelectric layer, an upper electrode layer on an upper side of the piezoelectric layer, and a lower electrode layer facing at least a portion of the upper electrode layer with the piezoelectric layer interposed therebetween. A fixing portion is disposed on the beam portion to sandwich the end portion of each beam portion between the fixing portion and the base portion. The fixing portion overlaps at least a portion of the base portion in an up-down direction, and extends to protrude from the base portion in an extending direction of the beam portion.
