PROBLEM TO BE SOLVED: To provide a backing material for probes which fully absorbs ultrasonic waves emitted from a rear face of a piezoelectric element, thereby preventing reflection, serves also to take out an electrode, achieves sure electric connection and enhances workability and, an ultrasonic probe using the material. SOLUTION: A plurality of bamboo blind-like metallic thin plates having many unit conduction electrodes 8 extended from a coupling part 7 are disposed in parallel in a backing material 3. The coupling part of the bamboo blind-like metallic thin plates is exposed to a surface of the backing material. Extended end parts of the unit conduction electrodes are exposed or projected to an outer surface except for the surface of the backing material. The backing material 3 for probes is constituted in this manner. A piezoelectric plate is fixed onto the surface of the backing material, which is divided in a first dimensional and a second-dimensional directions. |
