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.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.COPYRIGHT: (C)2013,JPO&INPIT【課題】照射対象によって容器を換えるだけで、超音波を使用した様々なアプリケーションに対応する。【解決手段】一方向に開放された開口を有するとともに、壁面の少なくとも一部に超音波を透過する超音波透過膜5を有し、超音波を伝播する超音波伝播液16を貯留する容器3を着脱可能に取り付けて開口を閉塞する超音波照射デバイス2であって、容器3を取り付けた状態で、該容器3内において超音波透過膜5に対向する位置に配置され、超音波を射出する射出面7を備える超音波素子8と、容器3を取り付けた状態で、該容器3内に存在する気泡を超音波素子8から射出される超音波の伝播領域外に制限する気泡制限部13とを備える超音波照射デバイス2を提供する。【選択図】図1
