Abstract

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.

Description

technical field [0001] Exemplary embodiments described herein relate to a method of manufacturing an ultrasonic sensor for detecting ultrasonic waves, the ultrasonic sensor, and a banknote processing apparatus including the ultrasonic sensor. Background technique [0002] Conventionally, a sheet processing apparatus (banknote processing apparatus) for counting and discriminating various types of sheets has been put into practical use. The sheet processing device takes the sheets inserted into the insertion port one by one, and conveys the sheets to the inspection device. The inspection equipment performs various processes on these sheets, and discriminates the state of the sheets. For example, the sheet processing apparatus can determine the type of the sheet and determine the authenticity of the banknote based on the inspection result of the inspection device. [0003] Also, the sheet processing apparatus can determine, for example, that a sheet to which a foreign substan...
