Abstract: The present invention relates to an anti-slip agent having a sufficiently large adhesion strength while being easily peeled off, that is, an anti-slip agent having a much larger resistance to the external force applied along the adhesion surface than to the external force applied perpendicular to the surface. The anti-slip agent of the present invention comprises 10 to 40 wt % of a volatile solvent, 1 to 5 wt % of a crystallization inhibitor, 1 to 10 wt % of a humectant, 0.5 to 5 wt % of a preservative, 0.1 to 1 wt % of a leveling agent, 1 to 10 wt % of a viscosity modifier and a biodegradable polymer material as residual.
