Zusammenfassung:	A metal-containing film-forming composition for lithography with an extreme ultraviolet ray or electron beam includes a compound and a solvent. The compound includes a metal element and an oxygen atom, and further includes a metal-oxygen covalent bond. The metal element in the compound belongs to period 3 to period 7 of group 3 to group 15 in periodic table. The solvent includes a first solvent component having a normal boiling point of less than 160° C. and a second solvent component having a normal boiling point of no less than 160° C. and less than 400° C. The solvent includes an alcohol solvent. A percentage content of the alcohol solvent in the solvent is no less than 30% by mass.
