Or, by sonic wave reception r-7 (converted to - with l energy, inject an in-7 run second wave, that is, sound l skin S1, into a material M made of a non-11, genus substance, and The sound wave receiver 4 or the sound wave receiver 7 receives the sound wave S1 or S2 and converts it into an electric signal Af3, which is amplified by the amplification width 2i5 according to the heart attack, and is displayed on the display 6. In this case, as shown in Fig. 3, if there is a defect in the test material M, the sound wave S1 received by the sound wave receiver 4 in that part is compared to the healthy part. Since the strength of the sound waves differs, by drawing a figure on the display 6 and comparing the two, it is possible to know whether there is a defect f in the material under test M.Fourth.
