PROBLEM TO BE SOLVED: To provide a method for manufacturing an electric wire connection structure capable of improving production efficiency of the electric wire connection structure having a tube terminal.SOLUTION: Disclosed is a method for manufacturing an electric wire connection structure 10 in which a tube terminal 11 includes a fitting part 20 and an electric wire connection 30, and the electric wire connection 30 of the tube terminal 11 and an electric wire 13 are crimped and joined together. This method includes the steps of: forming a cylindrical shaped electric wire connection 30 by pressing a strip and butt-welding a pressed cross section 33; inserting the electric wire 13 into the electric wire connection 30; crimping the electric wire connection 30 and the electric wire 13, and crushing the tip 32 of the electric wire connection 30 in order to seal the inside of the electric wire connection 30; and welding the tip 32 of the crushed electric wire connection 30, and then welding the fitting part 20 to this tip 32. |
