PROBLEM TO BE SOLVED: To efficiently diffuse heat.SOLUTION: An ultrasonic probe according to the embodiment includes a heat source, a first heat radiation member, and a first heat conduction member. The heat source is arranged on a tip end side in a housing and generates heat. The first heat radiation member is arranged on a back surface side of the heat source and is thermal contact with the heat source. The first heat conduction member extends along at least either the back surface or the side surface of the first heat radiation member and includes a first part in thermal contact with the first heat radiation member and a second part conducting heat the first part has received from the first heat radiation member to a rear end side of the housing.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】熱を効率的に拡散させることができる。【解決手段】本実施形態に係る超音波プローブは、熱源と、第1放熱部材と、第1熱伝導部材とを含む。熱源は、前記筐体内の先端側に配置され、発熱する。第1熱放熱部材は、前記熱源の背面側に配置され、前記熱源と熱的に接触する。第1熱伝導部材は、前記第1放熱部材の背面および側面のうちの少なくとも1つに沿って延在し、前記第1放熱部材と熱的に接触する第1部分と、該第1部分が該第1放熱部材から受けた熱を前記筐体の後端側に伝導する第2部分とを含む。【選択図】図1
