PROBLEM TO BE SOLVED: To simultaneously manufacture substrates with different thickness or different numbers of layers within the same work through a substrate manufacturing method for manufacturing substrates. SOLUTION: When manufacturing a substrate by laminating a plurality of elements (core materials 1a, 1b, 3a, 3b, prepregs 2a-2c, copper foils 4a-4d, removers 5a, 5b and inner layer patterns 11a-11c, 12a-12j); a substrate surface is divided into a plurality of areas, the removers 5a, 5b are provided in a plurality of elements laminated within at least one area, the substrate is divided for each area after laminating and pressing the substrate, and the substrate is manufactured with the less number of layers by removing unwanted portions using the removers in the area where the removers are provided, in comparison with the area in which the removers are not provided.
