Claim Text:
1. An ultrasonic probe comprising: an element part for transmitting and receiving ultrasonic waves; a relay cable connected to the element part, for transmitting a signal to the element part; liquid for transmitting ultrasonic waves; a frame and a window constituting a housing part in which the element part and the relay cable are housed, the liquid being sealed inside the housing part; and an oscillation mechanism part for oscillating the element part, wherein the oscillation mechanism part has a rotation axis configured to provide oscillation movement of the element part and a supporting plate that connects the rotation axis and the element part, the relay cable has a S-shape or a reversed S-shape with two arc-shaped parts in a plane perpendicular to the rotation axis, one end of the relay cable is connected to a cable connecting surface of the element part facing the rotation axis and, when the element part is positioned at a middle of a scanning range, in a connected portion with the element part, the relay cable is drawn from a point connected to the element part in a direction substantially parallel to the cable connecting surface, the rotation axis is located at a curvature center of at least one of the arc-shaped parts, a part of a side face of the rotation axis faces the arc-shaped part, and the remaining part of the side face of the rotation axis does not face the arc-shaped part, the frame is placed on an opposite side of the rotation axis from the element part, and is parallel to the cable connecting surface of the element part when the element part is positioned at the middle of the scanning range, the other end of the relay cable is fixed to the frame in a direction parallel to the surface of the frame, and the relay cable is electrically connected to an outer portion of the housing part with the liquid sealed in the housing part in a fixed part between the relay cable and the frame.
