<P>PROBLEM TO BE SOLVED: To provide a method for manufacaturing of a rubber sheet material for a floor which easily makes possible the exhibition of a pattern such as a planned shape or the like on the surface of the rubber sheet material for the floor. Ž<P>SOLUTION: In the method for manufacturing of the rubber sheet material for the floor, a surface sheet material is laminated on the back sheet material which uses an unvulcanized rubber sheet, and the surface sheet material uses the unvulcanized rubber sheet having a hole which penetrates both the front and the back. Then a layered product is formed in the hole of the surface sheet material, and an unvulcanized rubber sheet piece is engaged with the layered product, and the unvulcanized rubber sheet piece is formed so that it includes the different feel and texture from the surface sheet material. Then the layered product is pressurized, and vulcanization is performed. Thus, the rubber sheet material for the floor is manufactured by integrating the surface sheet material, the back sheet material, and the rubber sheet piece into a single piece.
