Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a biodegrable film which can be preferably used as a mulch film for agriculture or a sheet for fumigating a pine weevil, and to provide especially a polylactic acid-based film which can achieve both biodegrability and productivity.SOLUTION: The film is formed of a composition containing polylactic acid-based resin. The composition contains 30 mass% or more of polylactic acid-based resin in 100 mass% of total components of the composition. The polylactic acid-based resin has a maximum value of at least one molecular weight peak in a region having a molecular weight of 100,000 or more, and a maximum value of at least one molecular weight peak in a region having a molecular weight of less than 100,000 in its molecular weight distribution.
