To provide an ultrasonic probe and an ultrasonic diagnostic device capable of inhibiting heat generated in the vicinity of a contact surface with a subject from being transmitted to the subject.SOLUTION: An ultrasonic probe 100 includes: a plurality of vibrators 10 arrayed in a right-left direction X; a support part 11A for supporting a second surface on a side opposite to a first surface on a side that the vibrators 10 transmit/receive ultrasonic waves; an acoustic lens 13 disposed on a side opposite to a support part 11A side with respect to the vibrators 10; an acoustic matching part 12 disposed between the vibrators 10 and the acoustic lens 13; and a connection part 11B for connecting a region of at least part of one or both of a first end surface S1 and a second end surface S2 with the support part 11A with both end surfaces of the acoustic matching part 12 in a front-back direction Y intersecting with a right-left direction X and a vertical direction Z as the first end surface S1 and the second end surface S2. Heat conductivity of the support part 11A and the connection part 11B is higher than that of the acoustic lens 13.SELECTED DRAWING: Figure 2 【課題】被検体との接触面近傍で生じる熱が被検体に伝達されるのを抑制することのできる超音波プローブ及び超音波診断装置を提供する。【解決手段】超音波プローブ１００は、左右方向Ｘに配列された複数の振動子１０と、振動子１０が超音波を送受信する側の第１面とは反対側の第２面を支持する支持部１１Ａと、振動子１０に対して支持部１１Ａ側と反対側に配置された音響レンズ１３と、振動子１０と音響レンズ１３の間に配置された音響整合部１２と、左右方向Ｘ及び上下方向Ｚに交差する前後方向Ｙにおける音響整合部１２の両端面を第１端面Ｓ１及び第２端面Ｓ２とし、第１端面Ｓ１及び第２端面Ｓ２の一方又は両方のうちの少なくとも一部の領域と支持部１１Ａとを接続する接続部１１Ｂと、を備え、支持部１１Ａと接続部１１Ｂは、音響レンズ１３よりも熱伝導率が高い。【選択図】図２
