Abstract
An ultrasonic inspection method that includes arranging an ultrasonic transmission element and an ultrasonic reception element symmetrically in relation to a straight line in a diameter direction orthogonal to the cylinder axis of a cylindrical inspection object, the inspection object being interposed between the ultrasonic transmission element and the ultrasonic reception element; transmitting ultrasonic waves from the ultrasonic transmission element at a plurality of positions in the diameter direction; receiving by the ultrasonic reception element the ultrasonic waves transmitted from the ultrasonic transmission element and transmitted through the inspection object by propagating through the inside of the inspection object; and inspecting the inspection object on the basis of a reception signal of the ultrasonic waves received by the ultrasonic reception element.
