PROBLEM TO BE SOLVED: To provide a multiple-patterning wiring board that surely produces an individual wiring board having no acute angle portions for its each corner and being strong against cut-outs and cracks, obtained by separating the multiple-patterning wiring board into the individual wiring boards, and to provide a manufacturing method of the multiple-patterning wiring board. SOLUTION: The multiple-patterning wiring board K1 comprises: a plurality of wiring boards 1 for showing a rectangular shape in a plan view; a lug section 16 positioned around the plurality of wiring boards 1; and a nearly triangular through hole 14 in a plan view that includes a straight hypotenuse 11 for chamfering each corner for each wiring board 1 and has a round of 0.2-0.5 mm in radius (r) for each acute angle section 12. In the multiple-patterning wiring board K1, the acute angle position 12 is formed at the lug section 16. COPYRIGHT: (C)2008,JPO&INPIT
