An epoxy resin composition capable of reducing the surface roughness of a roughened cured body and reducing the linear expansion coefficient of the cured body even when the inorganic content is small, and curing. Provide the body. An epoxy resin composition comprising an epoxy resin, a phenol resin having a triazine skeleton, silica, and a maleimide compound, wherein the phenol resin has a weight average molecular weight of 1,500 or less, and heating the epoxy resin composition The cured body 1 is formed by roughening after preliminary curing.
