Provided are: a mold release film that is for use in mold formation, and that is characterized by being provided with a mold release layer comprising composition (I) or composition (II) disposed on a base material film; and a mold formation method using same. Composition (I) comprises: a compound (a) containing an alkyl group having eight or more carbon atoms; and a crosslinking agent (b). Composition (II) comprises a compound ([alpha]) that contains an alkyl group having eight or more carbon atoms and an ethylenically unsaturated group. By this configuration, it is possible to provide an inexpensive mold release film that is for use in mold formation and that exhibits favorable release properties after the hardening of a sealing material in the process of mold formation.
