Abstract
PURPOSE:To lead ultrasonic-wave oscillation out of an oscillator efficiently by forming electrodes, which generate a surface acoustic wave, directly on an elastic material subtrate by vapor deposition, etc. CONSTITUTION:On the surface of an elastic material substrate 50 made of quartz, a metallic film is vapor-deposited by using a mask pattern to form comb- shaped electrode elements 51 and 52 for generating a surface acoustic wave. This probe 56 is equipped to a holder and a high-frequency signal is applied to the electrode elements 51 and 52 so that a surface wave propagates on the elastic material substrate made of quartz. Then, the surface wave travels to the reverse surface efficiently through a junction surface 55 formed on a curved surface to reach the surface of a body 59 to be measured adhered to the reverse surface. If there is a flaw, the surface wave is reflected at the flaw, so the position of the flas is found by the resulting echo. The surface wave passed through the surface to be measured, on the other hand, is absorbed by a surface-wave absorber 57. Consequantly, even an extremely this body is measured and the sensitivity of measurement is improved.
