PROBLEM TO BE SOLVED: To provide a membrane material for advertisement which does not put so much burden on the environment in disposal after removal.

SOLUTION: The membrane material for advertisement is formed by coating one surface of a membrane substrate which is a knitted fabric obtained by knitting polylactic acid fibers having biodegradability with a coating layer formed by coating application of a printability improving agent which is a polylactic acid emulsion having the biodegradability. A flame retardant is included in the coating layer at 20 to 30 to 100 pts.wt. of the printability improving agent. The membrane substrate is a sheet inserted with warp and weft and is formed as a meshed sheet having an opening size of 0.5 to 5 mm on one side.
