Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a floor tile for guidance of a visually handicapped person which is environmentally conformable and excellent in a decorative design manner. SOLUTION: Suspension polymer vinyl chloride resin composition as main constituent and the resin composition of which a color tone is different from that of the main component are heated and kneaded to prepare a gel block. Otherwise the main constituent and synthetic resin granular material of which a melting point is higher than that of the resin composition are heated and kneaded to prepare the block. Thereafter, the block is ground, and classified to prepare a granular patterned composition. The patterned composition is filled in high density into a mold 1 wherein an irregularity for guidance of a visually handicapped person is formed on an inner surface. A backing material 8 is placed on the filled patterned composition 6, which is pressurized by heating at once with a press machine 2 to mold a marble toned or sandy toned floor tile for visually handicapped person.
