PURPOSE:To provide a printed circuit board such as a double-sided printed circuit board, a multilayer printed circuit board, etc., Which can be manufactured by a dry process in which a waste liquid processing problem of plating solution, etchant, cleaner, etc., is eliminated. CONSTITUTION:At least two or more single layer printed circuit boards 8 each having a resin base material 1, a circuit pattern 2 formed on the surface of the material 1, and a folded part 7 having a conductive part 6 formed by folding desired parts of the pattern 2 and the material 1 and integrated with the pattern 2, are laminated, and the patterns 2 of the adjacent board 8 are connected through the part 6 of the folded part 7. |
