PROBLEM TO BE SOLVED: To solve the problems that one of failure and operation troubles occurring due to particles and dust in terms of the configuration of equipment where a printed circuit board is incorporated in board material dust being generated from the end face of the printed circuit board, and it is necessary to use a metal base or to cover the substrate itself by molding for incorporated the printed circuit board in equipment for which particles, dust, or the like should be avoided for increasing costs. SOLUTION: Marking printing is made by ultraviolet curing type ink 2 for coating around a V-cut machining line 1 in a printed circuit board material, and then the generation of board material dust from the end face of a V-cut part can be prevented as a method for manufacturing the printed circuit board to be subjected to V-cut machining.
