<P>PROBLEM TO BE SOLVED: To provide a medical guide wire which keeps the distal end portion excellent in conformability, and the proximal end portion following to the distal end portion excellent in torque transmitting property, and shows a reduced change in outer diameter near the joint including a joint for connecting the distal end portion and the proximal end portion. <P>SOLUTION: The distal end side member 12 of the medical purpose guide wire has a part worked in a tapered shape so as to taper toward the distal end side end face 12a, the long hole 13 into which the distal end side member 11 can be inserted is provided in the axial line direction of the proximal end member 12 in the distal end side end face 12a of the proximal end member 12, the part of the distal end side member 11 including the distal end side end face 11a is inserted into the long hole 13, the gap 15 into which a brazing filler metal 14 can intrude is formed between the distal end side member 11 and the distal end side end face 12a of the proximal end side member 12, the coiled wire material 16 having substantially the same outer diameter of the distal end side end face 12a of the proximal end side member 12 is secured so as to cover a part of the outer periphery of the distal end side member 11, the distal end member 11 and the proximal end side member 12 is connected by the brazing filler metal 14 intruding from the gap 15. <P>COPYRIGHT: (C)2007,JPO&INPIT |
