- 摘要：
PROBLEM TO BE SOLVED: To irradiate a required part with strong ultrasonic waves and to irradiate a wide range with ultrasonic wave.
SOLUTION: The ultrasonic element 110 of the ultrasonic irradiation apparatus functions as a piezoelectric element having a curved surface in a concave lens shape in an area as shown in Fig.A and a piezoelectric element in a planar shape in an area as shown in Fig.B. Thereby, the ultrasonic waves are converged to a focus indicated by O, and energy given by the ultrasonic waves per area of the piezoelectric element is high at the focus. Whereas, the given energy is low in a range where non-converged ultrasonic waves are propagated, however the area to be irradiated with the ultrasonic waves per area of the piezoelectric element is large. Thus, the ultrasonic irradiation apparatus is provided which can irradiate a part required to be irradiated with strong ultrasonic waves with the converged ultrasonic waves and irradiate a part not required to be irradiated with the strong ultrasonic waves with the non-converged ultrasonic waves when the ultrasonic element 110 is used.
