1. An ultrasonic wave generation device comprising:
an ultrasonic wave generation source configured to generate an ultrasonic wave;
an ultrasonic wave condensation part configured to condense the ultrasonic wave generated from the ultrasonic wave generation source; and
a waveguide configured to allow transmission therethrough of the ultrasonic wave condensed by the ultrasonic wave condensation part, wherein
the ultrasonic wave condensation part has a first reflection surface located to be opposed to the ultrasonic wave generation source and a second reflection surface located to be opposed to the first reflection surface,
the first reflection surface reflects the ultrasonic wave, which has been generated from the ultrasonic wave generation source, toward the second reflection surface,
the second reflection surface reflects the ultrasonic wave, which has been reflected by the first reflection surface, toward the waveguide so as to introduce the ultrasonic wave into the waveguide,
the waveguide protrudes from the first reflection surface to a side opposite to the second reflection surface, and
a recessed portion is formed to be recessed from the first reflection surface to the second reflection surface side along an outer circumferential surface of the waveguide.
