PROBLEM TO BE SOLVED: To provide an ultrasonic cleaning apparatus with a waterproof mechanism, capable of suppressing heat generation in an ultrasonic vibration part. SOLUTION: When the ultrasonic vibration part 14 is overloaded, a control to lower a power supply is conducted by an overload detection circuit 32 and an oscillation circuit 31. In this way, heat generation in the ultrasonic vibration part 14 can be prevented by detecting an overload state and reducing the amount of power supply. Thus, an ultrasonic cleaning apparatus that does not give unpleasant feeling to a user because heat generation is suppressed and gives an ease of handling to a user can be realized.
