Abstract

One object of the present invention is to provide a pattern transferring mold which can provide a starting area of mold release easily and certainly and a pattern transferring apparatus with the same. A pattern transferring mold is disclosed which is used in a pattern transferring apparatus that brings the mold into contact with a photo-curing resin on a substrate and cures the photo-curing resin by light irradiation to transfer a pattern formed on the mold onto the photo-curing resin. The mold comprises a bottom face which contacts the photo-curing resin, the bottom face portion including a first area in which the pattern is formed and a second area formed outside the first area. The mold has a mold-releasing shape in the second area, the mold-releasing shape providing a starting area of mold release from the cured photo-curing resin.
