Abstract
An ultrasonic wave inspection device includes: a transmitter that outputs ultrasonic waves toward an inspection object; a receiver that receives at least first ultrasonic waves passed through the inspection object, among the ultrasonic waves output from the transmitter; a member that regulates a second propagation path, the second propagation path being a portion of propagation paths through which the output ultrasonic waves reach the receiver, and the second propagation path being different from a first propagation path through which the first ultrasonic waves reach the receiver; and a signal controller that extracts ultrasonic waves of a predetermined time segment from at least the first ultrasonic waves, the predetermined time segment starting from a time when the first ultrasonic waves is received.
