A control device for an ultrasonic apparatus includes: a reference value setting section that sets a reference value based on either the reflectance of an ultrasonic wave reflected from the interface with the air or the reflectance of an ultrasonic wave reflected from the interface with a measurement target a reference period setting section that sets a reference period ended at the earlier time than the time of receiving an ultrasonic wave that is transmitted from an ultrasonic transducer element and is reflected from the measurement target and a peeling detecting section that detects peeling of the ultrasonic transducer element by comparing a reception signal, which is output from the ultrasonic transducer element in the reference period, with the reference value.
