ABSTRACT:
A shockwave generator is adapted to be coupled to an object through a liquid medium for ultrasound transmission to generate a shockwave in the object. The shockwave generator comprises a piezoelectric element having an ultrasound radiating surface, an acoustic matching layer formed on the ultrasound radiating surface of the piezoelectric element, a fluorine-resin coating layer formed on the acoustic matching layer and a bag provided in front of the ultrasound radiating surface of the piezoelectric element and holding water for ultrasound transmission, where the water is held in contact with the fluorine-resin coating layer.
