A resist underlayer film composition for lithography, including: a silane: at least one among a hydrolyzable organosilane, a hydrolysis product thereof, and a hydrolysis-condensation product thereof, wherein the silane includes a silane having a cyclic organic group containing as atoms making up the ring, a carbon atom, a nitrogen atom, and a hetero atom other than a carbon and nitrogen atoms. The hydrolyzable organosilane may be a hydrolyzable organosilane of Formula (1), wherein, at least one group among R1, R2, and R3 is a group wherein a —Si(X)3 group bonds to C1-10 alkylene group, and other group(s) among R1, R2, and R3 is(are) a hydrogen atom, C1-10 alkyl group, or C6-40 aryl group; a cyclic organic group of 5-10 membered ring containing atoms making up the ring, a carbon atom, at least one of nitrogen, sulfur or oxygen atoms; and X is an alkoxy group, acyloxy group, or halogen atom.
