Disclosed is rubber clay for handicrafts. The rubber clay does not stick to the hands because it is manufactured by using a non-stick, inorganic compound having excellent transparency as the main component, the rubber clay is reusable because it does not harden even when a structure (model) made of the rubber clay is left for a long time, and the rubber clay may be represented in a wide range of colors. To this end, the rubber clay for handicrafts according to the present invention contains 60 to 80% by weight of a gel-type silicone base, based on the total weight of the rubber clay, wherein the gel-type silicone base consists of a mixture of siloxanes and silicones, dimethyl, methylvinyl, and vinyl group-terminated; 15 to 35% by weight of a plasticity adjuster, based on the total weight of the rubber clay, wherein the plasticity adjuster contains powder-type silica to control hardness; 1 to 5% by weight of an oil-type anti-cracking agent, based on the total weight of the rubber clay, consisting of polydimethylsiloxane to prevent cracking; and 0.1 to 1% by weight of an antimicrobial agent to prevent propagation of bacteria.
