Abstract
In an ultrasonic measuring method for measuring the thickness of a coating material applied by coating to one surface or both surfaces of a substrate made of a metal so as to provide a coated product, a pair of first ultrasonic sensor and second ultrasonic sensor are provided such that the first ultrasonic sensor is placed on one side of the coated product, as viewed in its thickness direction, via an air layer, while the second ultrasonic sensor is placed on the other side of the coated product, via an air layer, and the thickness of the coating material is measured by transmitting ultrasonic waves between the first and the second ultrasonic sensors. A flat-type transmitting sensor that permits propagation of unfocused ultrasonic waves is used as the first ultrasonic sensor, and a flat-type receiving sensor that permits propagation of unfocused ultrasonic waves is used as the second ultrasonic sensor.
