In a sound test object, a phased array probe 2 is arranged in advance on one side of a sound welded part, and a plurality of traverse waves focused on an arbitrary point is transmitted by making angles of refraction to be different from each other so as to prepare sound part data, and the maximum value of the reflection signal is obtained as a reference value. In an inspection object 100, the phased array probe 2 is arranged on one side of a welded part 101, and the plurality of traverse waves focused on the arbitrary point is transmitted by making angles of refraction to be different from each other so as to prepare inspection part data. A signal strength ratio is obtained by dividing the inspection part data by the reference value. When the signal intensity ratio is equal to or more than a specified value, the inspection object is determined to be defective.
