Zusammenfassung:This ultrasonic oscillation probe is an ultrasonic oscillation probe for transmitting ultrasonic vibration. A first region where the crystal grain size is relatively small and a second region where the crystal grain size is relatively large are respectively formed in at least one place. A method for manufacturing an ultrasonic oscillation probe respectively forms a first region where the crystal grain size is relatively small and a second region where the crystal grain size is relatively large in at least one place and heats a portion of the ultrasonic oscillation probe to a grain coarsening temperature or higher of a material that forms the ultrasonic oscillation probe, to form the second region.
