<P>PROBLEM TO BE SOLVED: To provide an ultrasonic irradiation device that is adapted to various applications using ultrasonic waves only by changing a container depending on the subject to be irradiated. <P>SOLUTION: The ultrasonic irradiation device 2 includes a container 3 which is detachably attached. The container 3 has an opening opened in one direction and an ultrasonic transmission film 5 for transmitting ultrasonic waves on at least one part of a wall surface, and which holds an ultrasonic wave propagation liquid 16 for propagating the ultrasonic waves, to close the opening. The ultrasonic irradiation device 2 includes: an ultrasonic wave element 8 with the container 3 attached thereto which is disposed in the container 3 in a position opposing the ultrasonic transmission film 5 and which has an irradiation surface 7 for radiating the ultrasonic waves; a bubble restricting part 13 with the container 3 attached thereto which regulates bubbles in the container 3 to areas outside a propagation region of the ultrasonic waves emitted from the ultrasonic wave element 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
