PROBLEM TO BE SOLVED: To adhere a heat conduction member to a back surface of a backing member by pressurization and to improve heat radiating effects without making an assembly tool large-sized and complicating an assembly process.SOLUTION: The ultrasonic probe includes: a backing member 11 adhered to the back surfaces of a plurality of vibrators 9 a case 13 which has a head part 31 for housing the plurality of vibrators 9 and the backing member 11 and has a grip part 33 formed integrally with the head part and the heat transfer member adhered to the backing member 11. The case 13 of the head part 31 has an opening on the side of an ultrasonic transmission/reception surface side of the plurality of vibrators 9. The heat transfer member comprises a back surface heat transfer member 41 positioned at the head part and a back surface heat transfer member 43 which is thermally connected to the back surface of the back surface heat transfer member 41 and is housed so as to extend from the head part 31 to the grip part 33. The back surface heat transfer member 43 is fixed to the back surface of the back surface heat transfer member 41 with a screw 51.COPYRIGHT: (C)2013,JPO&INPIT【課題】バッキング部材の背面に伝熱部材を押圧接着するとともに、組立冶具を大型化することなく、組立工程を煩雑化することなく、放熱効果を向上する。【解決手段】複数の振動子9の背面に接着されたバッキング部材11と、複数の振動子9とバッキング部材11を収容するヘッド部31に一体形成された把持部33とを有するケース13と、バッキング部材11に接着された伝熱部材とを備え、ヘッド部31のケース13は、複数の振動子9の超音波送受信面側に開口を有し、伝熱部材は、ヘッド部に位置された背面伝熱部材41と、背面伝熱部材41の背面に熱的に接続されてヘッド部31から把持部33にわたって収容された背面伝熱部材43とからなり、背面伝熱部材43が背面伝熱部材41の背面にねじ51で固定される超音波探触子。【選択図】図2
