With said distance kept constant, normal direction control is performed with the probe 1. The central axis of an ultrasonic wave beam is made to agree with the direction of the normal line on the surface of the body to be checked. Thereafter, ultrasonic flaw detection is executed under this state. When the ultrasonic wave beam is irregularily reflected by the effect of a flaw and the like in the surface of the body to be checked 15 during the period and the reflected wave cannot be received, constant distance control and normal direction control are performed at least at two points before and after the position of said flaw so as to hold said position. The distance and the normal direction at the position of the flaw undergo interpolation based on said controls. Thus the flaw detection is performed at the position of the flaw.
