Abstract: An ultrasonic measurement device includes an ultrasonic transceiver transmitting an ultrasonic wave and receiving a reflected wave from a target so as to output a reception signal, a scanner moving a transmission/reception position where the ultrasonic transceiver transmits and receives the ultrasonic wave along a first direction, and a position measurer measuring a position of the target. When the position measurer detects a plurality of reception signals corresponding to a plurality of reflection components caused by a difference in distances from the target at a first transmission/reception position in the first direction, the position measurer selects the reception signal based on a ratio between a voltage of the reception signals at a comparison transmission/reception position different from the first transmission/reception position and a voltage of the reception signals at the first transmission/reception position, and measures the position of the target based on the selected reception signal.
