Abstract
A remedial ultrasonic wave generating apparatus which allows highly efficient dispensation of a medicine without complicated preparations is provided. An ultrasonic wave generating apparatus for supplying an ultrasonic wave signal to a remedial ultrasonic oscillation element comprising an ultrasonic wave signal generating for generating an ultrasonic wave signal whose frequency randomly changes. The ultrasonic wave signal generating is constituted by, for example, a plurality of oscillation circuits oscillating at different frequencies and a switching circuit for randomly selecting one of the outputs of these oscillation circuits based on the output of a random number generating circuit.
