PROBLEM TO BE SOLVED: To provide a manufacturing method of a wired ring having excellent joining strength at a distal end of a wire with respect to a ring member, a manufacturing method of distal-deflecting movable catheter including the wired ring, and a jig for manufacturing the wired ring.SOLUTION: A silver brazing material 36 is attached to distal ends 30a and 31a of a first wire 30 and a second wire 31 projecting from a ring 32. Then, the wires 30 and 31 are axially moved along fitting grooves 44 and 45, and the distal ends 30a and 31a of the wires 30 and 31 to which the silver brazing material 36 is attached are drawn inside the ring 32, and brought into contact with the inner peripheral surface of the ring 32 respectively via the silver brazing material 36. The ring 32 is heated with it coming into contact with the distal ends, to melt the silver brazing material 36, so that the distal ends 30a and 31a of the first wire 30 and the second wire 31 are simultaneously joined with the ring 32 respectively. |
