Abstract
A wire loop type instrument for an endoscope having a plurality of elastic wires bundled together at distal and proximal ends thereof and adapted to form a loop shape as a whole. When withdrawn into the distal end of a sheath, the elastic wires are folded. When projecting from the distal end of the sheath, the elastic wires expand in the loop shape by their own elasticity. The elastic wires are inserted in a bundle into a pipe-shaped member at at least one of the distal and proximal ends thereof. The elastic wires are fixed to the pipe-shaped member by a fixing material such that portions of the elastic wires which are in the vicinity of the entrance of the pipe-shaped member are not fixed, but the elastic wires are fixed to the pipe-shaped member at portions thereof which are on the inner side of the vicinity of the entrance.
