To provide a biodegradable film capable of being heat-sealed even at a low temperature though it is a film having a laminated configuration which utilizes the usefulness of containing polylactic acid as a component of a front base material and the usefulness of containing polybutylene succinate in a sealant as the component.

The biodegradable film comprises a stretched film containing polylactic acid as a main raw material as the front base material 2, and has a laminated configuration where a sealant film 3 having biodegradability for the front base material 2 is pasted. The sealant film 3 comprises an aliphatic polyester resin and a polylactic acid resin as a molding material, and the aliphatic polyester resin and the polylactic acid resin are combined with the ratio of 80:20 to 20:80 in weight ratio.
