To provide a washing machine capable of generating mist by optimally controlling the vibration of an ultrasonic element.
This washing machine detects a horn current (a step S30), then determines whether a time of 32 msec elapses or not (a step S31), and repeats the detection of the horn current in the step S30 till the time of 32 msec elapses. Then, this washing machine calculates an average value of the horn currents Ih (a step S32). Whether a condition of -50 mAIh-Ih#50 mA is satisfied or not is determined (a step S34). When determining that a difference between the horn current calculated this time and the horn current calculated previously is small, namely the variation is scarcely recognized, this washing machine finishes a confirmation processing before tuning (a step S35).
