<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a long body for medical use, with which the long body for medical use can be easily and quickly manufactured with high yield. <P>SOLUTION: An electrolytic solution 41 and an insulating liquid 42 having insulation property and has a specific gravity larger than that of the electrolytic solution 41 are stored in the electrolytic cell 11 of an electrochemical machining apparatus 10 where the solution and the insulating liquid are separated from each other. A pre-machining long body 32 is set in the electrochemical machining apparatus 10 such that a portion for performing the electrochemical machining of the pre-machining long body 32 is immersed in the electrolytic solution 41 in the electrolytic cell 11 and a portion not performing the electrochemical machining of the pre-machining long body 32, which is located closer to the end side compared with the portion for performing the electrochemical machining, is immersed in the insulating liquid 42. The electrochemical machining is performed by energizing the electrolytic solution 41 with a reinforcing body layer 5 as an anode and with an electrode 17 as a cathode. Consequently, the portion of the reinforcing body layer 5 immersed in the electrolytic solution 41 is removed by the electrochemical machining, and the electrochemical machining is not performed in the portion of the pre-machining long body 32 immersed in the insulating liquid 42. <P>COPYRIGHT: (C)2011,JPO&INPIT |
