Abstract
An ultrasonic inspection device includes: a longitudinal ultrasonic sensor configured to emit and receive a longitudinal ultrasonic wave; and an ultrasonic transducer unit made of metal and having the shape of a polyhedron. The ultrasonic transducer unit includes: an output surface configured to be disposed facing an object to be inspected; an input surface on which the longitudinal ultrasonic sensor is disposed; and a conversion surface configured to, when the longitudinal ultrasonic wave input through the input surface is reflected by the conversion surface, convert the longitudinal ultrasonic wave into a transverse ultrasonic wave such that the transverse ultrasonic wave propagates toward the output surface, the conversion surface being tilted at a predetermined angle with respect to an in-plane direction of the output surface. Thermal conductivity of the ultrasonic transducer unit is lower than thermal conductivity of the object to be inspected.
