PROBLEM TO BE SOLVED: To provide a wiring material for a printed substrate of a low cost, which is satisfactory in fixing operativity and in performance stability. SOLUTION: In a wiring material for a printed substrate, having a wiring material for electrically connecting a first printed substrate 1 and a second printed substrate 2, and an retrofitting type ferrite core 20 which is after- mounted on the wiring material, the wiring material is constituted of a printed substrate 10, cut-out portions 12, 12' are provided to both side surfaces at a position for fixing the retrofitting type ferrite core 20 for a flat wire of the printed substrate 10 and the retrofitting type ferrite core 20 for a flat wire is disposed in the printed substrate 10 so as to make ferrite cores 22a, 22b of the retrofitting type ferrite core 20 of a flat wire enclose the part of the printed substrate 10 between the cut-out portions 12, 12'.
