An ultrasonic testing control method for controlling a probe, the probe including a transceiving surface that has a greater length in a length direction than in a width direction, and an array of ultrasonic elements provided on the transceiving surface, the probe emitting ultrasonic waves to a surface to be inspected of an object to be inspected, the surface to be inspected facing the transceiving surface, while moving in the width direction,

• each of the ultrasonic elements being formed in a shape so as to have a same length in the length direction and the width direction,
• the array of ultrasonic elements being arranged in a matrix in the length direction and the width direction, the method comprising the step of:
• in an emission unit corresponding to an ultrasonic element emission group defined by an array of the ultrasonic elements adjacent to each other in the length direction and an array of the ultrasonic elements adjacent to each other in the width direction and having a same number of the ultrasonic elements in the length direction and the width direction, emitting ultrasonic waves a large number of times while changing a position of the emission unit in the length direction from one end toward the other end in the length direction such that respective portions of the emission units overlap.

• each of the ultrasonic elements being formed in a shape so as to have a same length in the length direction and the width direction,
• the array of ultrasonic elements being arranged in a matrix at a predetermined inclination with respect to the length direction and the width direction, the method comprising the step of:
• in an emission unit corresponding to an ultrasonic element emission group defined by an array of the ultrasonic elements adjacent to each other in the length direction and an array of the ultrasonic elements adjacent to each other in the width direction and having a same number of the ultrasonic elements in the length direction and the width direction, emitting ultrasonic waves a large number of times while changing a position of the emission unit in the length direction from one end toward the other end in the length direction such that respective portions of the emission units overlap.
