PROBLEM TO BE SOLVED: To act always a predetermined sac pressure on a fracture part from the outer periphery toward the central direction by utilizing a retrenchment force to the longitudinal direction accumulated in a linear member for a medical treatment under an extended state and an expanding force to the diameter direction as the sac pressure. SOLUTION: A basic body in which a plurality of wires are arranged is made to be a spiral winding by having a space part inside and opening a gap part in the axial direction to form a spiral body being spirally wound, and the outer periphery of the spiral body is covered with a resin coating layer. Slip characteristics of the outer surface of the linear member for the medical treatment is improved by covering with the resin coating layer, and as the sliding resistance thereof with the intracorporeal tissue by body movement and pulsation movement after surgery can be suppressed low, bad influence on the intracorporeal tissue other than the site objective for the surgery can be lessened.
