PROBLEM TO BE SOLVED: To provide an ultrasonic probe for easily acquiring blood flow information by swinging a vibrator and to provide an ultrasonic diagnostic apparatus.SOLUTION: The ultrasonic probe includes: a vibrator unit 11 for transmitting and receiving ultrasonic waves to/from a subject P a swing arm 25 for swingably holding the vibrator unit 11 and a drive means of a first motor 21 for swing-driving the swing arm 25 to swing the vibrator unit 11. The swing arm 25 holds the vibrator unit 11 at a predetermined angle θ so that the ultrasonic waves can be transmitted and received in a swing direction between the swing direction of the vibrator unit 11 and the subject direction of the subject P which is a direction opposite to the direction of the swing center of the vibrator unit 11 orthogonal to the swing direction, and in the directions other than the subject direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】振動子を揺動して血流情報を容易に得ることが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】被検体Pに対して超音波の送受波を行う振動子部11と、振動子部11を揺動可能に保持する揺動アーム25と、揺動アーム25を揺動駆動して振動子部11を揺動させる第1モータ21と、の駆動手段とを備え、揺動アーム25は、振動子部11の揺動方向とこの揺動方向に直交する振動子部11の揺動中心の方向とは反対の方向である被検体Pの被検体方向の間の前記揺動方向及び前記被検体方向以外の方向に超音波の送受波が可能なように所定の角度θで振動子部11を保持する。【選択図】 図2
