Abstract: A photosensitive composition remover used for removal of an uncured photosensitive composition, which remover includes 1 to 80 percent by mass of at least one type of aromatic hydrocarbon having 9 carbon atoms or more within the molecule. The photosensitive composition remover further includes an aprotic polar solvent and/or another solvent other than aprotic polar solvents. The photosensitive composition remover is effective for removal of an uncured photosensitive composition film deposited at the periphery, edges, or back of a substrate or removal of an uncured photosensitive composition deposited at the surface of system members or equipment in a process for forming a photosensitive composition film on a glass substrate, a semiconductor wafer, or the like.
