PROBLEM TO BE SOLVED: To provide an antiviral agent which has reduced cytotoxicity, is available at a low cost and thus is different from conventional ones, though many antiviral actions by sulfated polysaccharides such as heparin have been investigated. SOLUTION: The antiviral agent contains a sulfated polysaccharide prepared by using a plant-originated polysaccharide such as cellulose or glucomannan, and sulfating 6-100% of the hydroxy groups of the raw material polysaccharide or a compound having the sulfated polysaccharide as a partial structure, especially cellulose sulfate or glucomannan sulfate.
