PROBLEM TO BE SOLVED: To provide a lead wire for a non-aqueous electrolyte electric cell, that, in the non-aqueous electrolyte cell, can sufficiently ensure insulating property between a lead conductor and a metallic layer of an envelope. SOLUTION: The lead wire 18a for the non-aqueous electrolyte electric cell is fused on the inner surface of envelope 14. The envelope 14 has a metallic layer 22 therein and is filled with a non-aqueous electrolyte medium 20, a positive electrode 30, and a negative electrode 32. The lead wire 18a comprises a lead conductor 19a electrically connected to the positive electrode 30, and an insulator 21a cladding the lead conductor 19a and fused on the inner surface of the envelope 14. The insulator 21a includes at least a cross-linked layer 23a made of cross-linked polyolefin resin. According to this invention, as the insulator 21a includes the cross-linked layer 23a made of the cross-linked polyolefin resin, when the lead wire 18a is attached by thermal fusion, a short between the lead conductor 19a and the metallic layer 22 of envelope 14 is sufficiently prevented due to the fusion of the insulator. |
