摘要
According to one embodiment, a method for manufacturing an ultrasonic sensor includes forming a first conductive layer on one side of a piezoelectric body having opposing sides; forming a second conductive layer on the other side of the piezoelectric body; forming a backing layer on the first conductive layer; forming a matching layer of a size corresponding to a size of a conveyed object to be detected on the second conductive layer; and providing at least one incision that cuts through the first conductive layer, the piezoelectric body, the second conductive layer and the matching layer, the incisions having a depth extending from the matching layer to at least the first conductive layer, to form a plurality of channels.
