摘要 |
Provided is an epoxy resin composition capable of reducing the surface roughness of the surface of a roughening-treated cured body. The epoxy resin composition includes an epoxy resin, a curing agent, and a silica component obtained by performing a surface treatment on silica particles using a silane coupling agent; and the epoxy resin composition does not include a curing accelerator, or includes a curing accelerator at a content equal to or less than 3.5 parts by weight to a total of 100 parts by weight of the epoxy resin and the curing agent. Mean particle diameter of the silica particles is equal to or less than 1 mum. An amount B (g) of the silane coupling agent used for surface treatment, per 1 g of the silica particles in the silica component, is within a range between 10% to 80% with regard to a value C (g) per 1 g of the silica particles, which is calculated by the following formula (X). C (g)/1 g of Silica Particles=[Specific Surface Area of Silica Particles (m2/g)/Minimum Area Coated by Silane Coupling Agent (m2/g)]Formula (X)
