Abstract

PURPOSE: To improve resolution by fixing square-plane shaped piezoelectric bodies to adjacent sides of a metal substrate of a rectangular elastic body and by coating two other sides, confronting to piezoelectric bodies, with resin obtained by mixing metal powder such as iron powder.
CONSTITUTION: Piezoelectric bodies 12 and 12', provided to two adjacent sides of metal substrate 11 of a rectangular elastic body, are in a rectangular plane shape of a PZT, etc., namely, in a book shape and fixed to substrate 11 by an adhesive such as epoxy resin. Further, resin 13 is molded on two other sides confronting piezoelectric bodies 12 and 12', and obtained by mixing metal powder such as iron powder into an epoxy-based adhesive. Consequently, no disturbance caused by a reflected wave occurs to substrate 11 and the output voltage signal of a detecting pen contains only signals of incident waves, so that the resolution can be improved.
