<P>PROBLEM TO BE SOLVED: To provide a guide wire having a distal end part surely habitually bent in a desired shape, and suppressing the increase of cost, even though the guide wire is formed of a superelastic Ni-Ti alloy. <P>SOLUTION: The guide wire 10 includes a core wire 20 having a distal end part at least made of superelastic Ni-Ti alloy, and a coil 30 made of a Pt (platinum)-based alloy or W (tungsten) arranged on the outer periphery of the distal end part of the core wire 20, the distal end part of the core wire 20 extends in a linear shape in an initial shape and the wire diameter D1 of a part of a predetermined length from the distal end tip thereof is 0.02 to 0.10 mm, a gap C1 of 0.01 to 0.08 mm is formed between the outer periphery of the part of a predetermined length from the distal end tip of the core wire 20 and the inner periphery of the coil, and the gap C2 between the adjacent coil wires 32, 32 of a part arranged on the outer periphery of the part of the predetermined length from the distal end tip of the core wire 20 of the coil 30 is 0.03 to 0.08 mm. <P>COPYRIGHT: (C)2011,JPO&INPIT |
