Abstract

PURPOSE:To obtain an ultrasonic probe which is easy to produce and inspect and can be used for the direct contact method and has reduced fluctuation of the focal distance caused by change of the refractive index of a lens dependent upon materials of the lens, temperature change, etc., by adding the plane lens utlizing diffraction phenomena to the ultrasonic probe. CONSTITUTION:Plane lens 6 obtained by forming white ring band 6a of an ultrasonic transmission region and black ring band 6b of an ultrasonic non-transmission region alternately into coaxial circles or ellipses is arranged in the face of ultrasonic vibrator 1 opposite to a inspected material. Then, the focusing point of the ultrasonic wave can be changed by expanding or contracting the whole ultrasonic transmission region 6a and ultrasonic non-transmission region 6b by a prescribed magnification.
