Claim:
1. A rolled film formation apparatus, comprising: a first chamber in which a first precursor is applied to a substrate; a second chamber in which a second precursor is applied to the substrate such that the first and second precursors react with each other and that an atomic layer is deposited on the substrate; a third chamber in which a purge gas for purging the first or second precursor is applied to the substrate; and a plurality of conveyance roller pairs positioned in the first chamber, the second chamber and the third chamber, and configured to convey the substrate, wherein each of the conveyance roller pairs includes a first roller and a second roller configured to sandwich the substrate in a thickness direction of the substrate, at least one of the first and second rollers has an outer peripheral surface having a surface unevenness, the surface unevenness is formed by a plurality of grooves formed on the outer peripheral surface of the second roller, the plurality of conveyance roller pairs is configured such that the substrate is moved back and forth among the first chamber, the second chamber and the third chamber, and that the atomic layer is deposited more than once on the substrate, and the grooves are formed in a direction parallel to an axis of rotation of the second roller.
