PURPOSE: A method for processing an outer shape of a band type printed circuit board is provided to increase the length of the band type printed circuit board by improving a blanking process and an outer shape process. CONSTITUTION: First to third circuit patterns are formed on a central region of a flexible substrate(3). The inner shape and the outer shape of the first circuit pattern are blanked at the same time. The inner shape and the outer shape of the third circuit pattern are blanked at the same time. The inner shape and the outer shape of the second circuit pattern are blanked at the same time. The outer shape of the second circuit pattern is partially overlapped with the outer shape of the first circuit pattern to form an overlapped blank region(12).
