【Task】 Provided is an epoxy resin composition from which a cured product having heat resistance and high thermal conductivity can be obtained. [Solution] Following formula (1) (Wherein, R represents a hydrogen atom or a methyl group, R 1 to R 4 are each independently hydrogen atom, a hydrocarbon group having 1 to 8 carbon atoms, a trifluoromethyl group, an aryl group or a methoxy group. The hardened | cured material obtained by hardening | curing the epoxy resin composition formed by containing the epoxy resin and hardening | curing agent represented by ()) was excellent in heat resistance, and had high heat conductivity. [Selection figure] None |
