A stepped substrate-coating composition for forming a coating film having filling property of a pattern and flattening property including a compound (E) having a partial structure (I) and a partial structure (II) having a hydroxy group formed by a reaction of an epoxy group with a proton-generating compound, a solvent (F), and a crosslinkable compound (H), wherein the partial structure (I) is from Formulae (1-1) to (1-5) or including a partial structure of Formula (1-6) combined with a partial structure of Formula (1-7) or (1-8), and the partial structure (II) is of the following Formula (2-1) or (2-2), wherein the compound (E) contains the epoxy and hydroxy group at a molar ratio (epoxy group)/(hydroxy group) of 0 or more and 0.5 or less, and contains the partial structure (II) so the molar ratio (partial structure (II))/(partial structure (I)+partial structure (II)) is 0.01 or more and 0.8 or less.
