PROBLEM TO BE SOLVED: To provide an antibacterial material having high antibacterial activity (antibacterial activity), excellent durability of antibacterial activity and excellent processing durability, and an antibacterial film using the antibacterial material. An antimicrobial material containing a high molecular polymer having a phosphonium sulfonate group represented by the following general formula (I) as a main component, and a film provided with a layer of the antimicrobial material on at least one surface is formed on a metal thin plate. After laminating, the laminated metal plate was immersed in distilled water at 95 ° C. for 2 hours, and the antibacterial material layer was placed inside with 18 layers as specified in JIS-Z-2248. An antibacterial material having a minimum inner radius T of 1 mm or less when subjected to 0 degree bending. Embedded image (In the formula, R 1 , R 2 , R 3 , and R 4 are an alkyl group or an aryl group, and at least one is an alkyl group having 10 to 20 carbon atoms.) |
