Zusammenfassung:	There is provided a composition for forming an EUV resist underlayer film which shows a good resit form. A resist underlayer film-forming composition for EUV lithography, including: polysiloxane (A) containing a hydrolyzed condensate of hydrolyzable silane (a); and hydrolyzable silane compound (b) having a sulfonamide structure, a carboxylic acid amide structure, a urea structure, or an isocyanuric acid structure. A resist underlayer film-forming composition for EUV lithography, including: polysiloxane (B) containing a hydrolyzed condensate of hydrolyzable silane (a) and hydrolyzable silane compound (b) having a sulfonamide structure, a carboxylic acid amide structure, a urea structure, or an isocyanuric acid structure. The polysiloxane (A) is preferably a co-hydrolyzed condensate of a tetraalkoxysilane, an alkyltrialkoxysilane and an aryltrialkoxysilane.
