PROBLEM TO BE SOLVED: To provide a multi-purpose rubber sheet low in cost manufactured by a process comprising forming a granular rubber member formed by pulverizing waste tires into a sheet-form as an elastic layer while effectively utilizing waste tires to prevent environmental deterioration. SOLUTION: The rubber sheet 10 is formed by forming an elastic layer 12 by mixing an adhesive 15 and the granular rubber member 14 formed by pulverizing the waste tires, applying the elastic layer 12 in layers on the surface of a substrate sheet 11, and drying it. Also a synthetic resin coating 21 may be added to the adhesive 15 to form a rubber sheet of a desired color and, after cutting, the rubber sheet may be re-processed to make a tiger-pattern sheet usable as a so-called safety sign serving for environmental safety and prevention of accidents.
