To provide a manufacturing method of a design panel having an uneven part and having patterns different from the whole applied to the uneven part, and to suppress the positional shift of the pattern of the uneven part with respect to the uneven part in the design panel.
The design panel has a hole to which the pattern different from the whole is applied and is manufacture by arranging the first sheet 2, which covers the side surface and outer edge part of the protrusion 51a of a fixed mold 51, to the protrusion 51a of a fixed mold 51, arranging to a second sheet material 3, to which a hole 3a having a size enough to overlap with the outer edge part 2b of the first sheet material 2 is formed, to the fixed mold 51, assembling the movable mold 52 forming a pair with the fixed mold 51 with the fixed mold 51 and the cavity part formed by both molds 51 and 52 is filled with a molten resin 4.
