PROBLEM TO BE SOLVED: To provide a thickness measuring device, capable of more accurately measuring the thickness of a measurement object. SOLUTION: Ultrasonic waves are transmitted to the measurement object, and the thickness of the measurement object is measured from the reflected wave. When the measurement object is a human body, the approximate thickness of the measurement object is estimated according to the information on the measurement object such as information on the height, information on percent of body fat, information on the peripheral diameter of a region as a measurement object, and information for specifying a region as a measurement object. According to the estimated approximate thickness, power of ultrasonic wave to be transmitted is controlled to correct measurement of thickness. COPYRIGHT: (C)2003,JPO
