PURPOSE:To obtain a probe having a high performance and a high mechanical strength by forming a composite piezoelectric material by packing an organic matter in a gap of a lot of columnar piezoelectric bodies arrayed at an interval to each other, and connecting an electrode attached to an adjacent columnar piezoelectric body, by a thin wire. CONSTITUTION:A columnar piezoelectric body 201 consisting of an inorganic piezoelectric material is arrayed at an interval to each other, an organic matter 202 is packed in a gap, and a composite piezoelectric material is formed. Subsequently, an electrode 203 is stuck to the upper face and the bottom face of the piezoelectric body 201, respectively, and the electrode 203 stuck to the adjacent piezoelectric body 201 is connected by a thin wire to at least one of the upper face or the bottom face. Therefore, an exposed part 204 of the organic matter is formed on the surface of the composite piezoelectric material. In this regard, the electrode 203 and the thin wire can be formed by means of screen printing or vapor deposition. In this way, the electrode on the organic matter is thinned, by which an electrical loss in the organic matter can be reduced, and a ultrasonic probe having a high performance and a high mechanical strength can be obtained. |
