PROBLEM TO BE SOLVED: To easily inspect defects by ultrasonic flaw detection by displaying only reflection waves from a defect clearly on a monitor without generating extra echoe waves causing inspection troubles. SOLUTION: An ultrasonic probe 1 is brought into contact with the surface of an object to be inspected, applies ultrasonic waves to the object, receives the ultrasonic waves reflected from the object, and detects defects being present in the object. The ultrasonic probe 1 comprises a transmission element 5 that orthogonally crosses a propagation direction, and generates SH waves as the ultrasonic waves being displaced in a direction in parallel with the surface of the object; and a light receiving element 6 that receives the SH waves generated from the transmission element 5 and are reflected from the object and is separately provided from the transmission element 5.
