A film-forming composition including a triazine ring-containing hyperbranched polymer with a repeating unit structure indicated by formula (1), and inorganic micro particles is provided. This enables the provision of a film-forming composition capable of hybridizing without reducing dispersion of the inorganic micro particles in a dispersion fluid, capable of depositing a coating film with a high refractive index, and suitable for electronic device film formation. (In the formula, R and R' are mutually independent and indicate a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar indicates a divalent organic group including either an aromatic ring or a heterocyclic ring, or both.) Composition filmogène comprenant un polymère hyper-ramifié contenant un cycle triazine ayant une structure de motifs répétitifs représentée par la formule (1), et des microparticules inorganiques. La composition filmogène obtenue est capable d'hybridation sans réduction de la dispersion des microparticules inorganiques dans un fluide de dispersion, peut former un film de revêtement ayant un indice de réfraction élevé, et se prête à la formation de films pour dispositifs électroniques. (Dans la formule, R et R' sont mutuellement indépendants et représentent un atome d'hydrogène, un groupe alkyle, un groupe alcoxy, un groupe aryle, ou un groupe aralkyle, et Ar représente un groupe organique divalent comprenant soit un cycle aromatique, soit un cycle hétérocyclique, ou les deux).
