PROBLEM TO BE SOLVED: To provide a method of connecting printed circuit boards whereby deterioration in strength of connected parts can be prevented. SOLUTION: The middle part of the intermediate part of a master board 1, the wiring circuits 10, 11 of which are printed to the right side and the left side of a base film 1A in the lengthwise direction, is vertically projected, ends 10A, 11A of the wiring circuits 10, 11 located to the left right and the left side are printed into projected parts 12, 13, respectively, vertically projected in a way of extending the ends 10A, 11A, and a printed circuit board 2 other than the master board 1 is arranged to the master board 1 so that electrodes 2A, 2B provided to the rear side of the printed circuit board 2 are in contact with the ends 10A, 11A printed into the projects 12, 13.
