PROBLEM TO BE SOLVED: To provide a triazine ring-containing polymer capable of achieving high heat resistance, high transparency, high refractive index, high solubility, and low volume shrinkage without adding a metal oxide, and for film formation including the same Providing a composition. For example, a polymer including a repeating unit structure having a triazine ring as represented by the following formula (24) has a very high refractive index and is suitable as a high refractive index material. .
