To provide a film for biodegradable protection that is useful for the protection of large articles that especially have complicated shapes such as automobiles and that has biodegradability and excellence in thermal resistance and shape followingness.

The film for protection consists of an adhesive layer provided on a supporting base material and the rear side of it and the supporting base material consists of a compound made up of a biodegradable plastic (component A) whose glass transition point is below 0 and the biodegradable plastic (component B) whose melting point is above 130. The blend ratio of A and B of the film for protection is 90-60:10-40 by a weight standard. The film for the protection is for the protection of an automobile body.
