Abstract

An ultrasonic transducer includes: an acoustic matching layer composed of a sheet-like member; a piezoelectric element having a plurality of piezoelectric elements arranged on the acoustic matching layer; and a plurality of blocks disposed adjacent to at least one end of the elevation direction of the piezoelectric element and containing an abrasive material. Thus, an ultrasonic transducer, an ultrasonic endoscope, and a manufacturing method of an ultrasonic transducer are provided, which prevent chipping and cracking when cutting the piezoelectric element, and have excellent performance.
