At least, an ultrasound probe and the receiving element layer in which electrodes are formed on both surfaces of the transmission element layer, opposite to the thickness direction, and the matching layer are stacked, the receiving element layer on both sides and a protruding portion protruding in the elevation direction from the upper and lower layers sandwiching the receiving element layer electrodes are respectively formed, the one ultrasonic wave, characterized in that it is formed by extending the protrusion at least one of the electrodes probe.少なくとも、送信素子層と、厚さ方向に対向する両面にそれぞれ電極が形成された受信素子層と、整合層と、が積層された超音波探触子であって、受信素子層は、両面にそれぞれ電極が形成された受信素子層を挟む上下の層よりエレベーション方向に突出した突出部を備え、電極のうち少なくとも一方は、突出部に延長して形成されていることを特徴とする超音波探触子。
