PURPOSE: A manufacturing method of an L-shaped member for a railway switch is provided to enhance mechanical strength, to reduce manufacturing processes and to manufacture an L-shaped member exactly according to the required dimensions by mechanizing manufacturing processes. CONSTITUTION: A manufacturing method of an L-shaped member for railway switch comprises the steps of: cutting a member plate(A) having a regular thickness into a regular sized L shape(B); forming an L-shaped member having a bent end to measure by putting the L shape on an L-shaped member form(C), then applying pressure; trimming a flash part(B-2) formed on the outer circumferential surface of the L-shaped member; and forming a through hole(B-3) at the center of a bent part(B-1) formed on the end of the L-shaped member.
