摘要： An anti-slip sheet to be used around water can be easily fixed onto the floor or bathtubs, etc., by simply adhering. The sheet resists curling (coiling) or separation, has low surface irritation on skin, and even under humid environment has excellent anti-slip properties. The anti-slip sheet includes a resin film having a Shore A hardness of 60 or higher and 82 or lower, a protrusion and indentation surface where the maximum value of the adjacent protrusions peaks are within the range of 10 microns or higher and 150 microns or lower, has a maximum height Rmax of the surface roughness within the range of 15 microns or higher and 90 microns or lower, and includes a top part reinforcing film positioned on the resin film on the side opposite to the protrusions and indentations containing surface which is harder than the resin film, and includes a bottom part adhesive layer positioned on the side of the top part reinforcing film that is opposite to the resin film
