To provide a composition useful for manufacturing a light-emitting element with excellent luminous efficiency and to provide a manufacturing method for the light-emitting element formed by using the composition.SOLUTION: A composition includes at least one compound A selected from the group consisting of a metal complex represented by formula (1) and a polymer compound A including a constitutional unit having a group made by removing one or more hydrogen atoms from the metal complex represented by the formula (1), a polymer compound B including a constitutional unit which is a specific siloxane group, and a solvent. A surface tension γ0 [mN/m] of the solvent at 25°C and a surface tension γ100 [mN/m] at 25°C when the solvent contains 100 mass ppm of the polymer compound B satisfy the relationship of γ0-γ100>1.0 [mN/m].SELECTED DRAWING: None 【課題】発光効率が優れる発光素子の製造に有用な組成物を提供する。当該組成物を用いて形成された発光素子の製造方法を提供する。【解決手段】組成物は、式（１）で表される金属錯体及び前記式（１）で表される金属錯体から水素原子１個以上を除いた基を有する構成単位を含む高分子化合物Ａからなる群より選択される少なくとも１種の化合物Ａと、特定のシロキサン基である構成単位を含む高分子化合物Ｂと、溶媒とを含有する組成物であり、前記溶媒の２５℃における表面張力γ0[ｍＮ／ｍ]と、前記溶媒が前記高分子化合物Ｂを１００質量ｐｐｍ含有する場合の２５℃における表面張力γ100[ｍＮ／ｍ]とが、γ0－γ100＞１．０[ｍＮ／ｍ]を満たす。TIFF2023143712000087.tif4591【選択図】なし
