Zusammenfassung:	A resist underlayer film-forming composition for lithography including a copolymer having a structural unit of the following Formula (1) to Formula (3), a crosslinking agent, an organic acid catalyst, and a solvent:(wherein R1s are independently a hydrogen atom or a methyl group, R2 is a C1-3 alkylene group, A is a protective group, R3 is an organic group having a 4-membered ring to 7-membered ring lactone framework, adamantane framework, tricyclodecane framework or norbornane framework, R4 is a linear, branched or cyclic organic group having a carbon atom number of 1 to 12 in which at least one hydrogen atom is substituted with a fluoro group and which optionally has at least one hydroxy group as a substituent).
