The present invention relates to a non-slip cotton sanitary pad, comprising a pad body, configured such that a cotton lining, an absorption pad and a waterproof cover are sequentially stacked, and a pair of wings protruding from both sides of the pad body. The pair of wings protruding from both sides of the pad body includes a fastener so that the wings are fastened together in a folded state on the same surface. The cotton sanitary pad is disposed such that the waterproof cover contacts an underwear. The waterproof cover includes a non-slip member on a surface contacting the underwear. The non-slip member is made of a silicone material, and is thermally fused to the waterproof cover. The fastener includes buttons or hook-and-loop closures, and the waterproof cover is subjected to polyurethane waterproof coating.
