To provide an epoxy resin composition which can form a cured material having low dielectric constant and low dielectric loss tangent in a radio frequency region, and a film obtained by using the epoxy resin composition. n An epoxy resin composition comprising: (A) at least one epoxy resin selected from the group consisting of a novolac epoxy resin having a phenolic skeleton and a biphenyl skeleton, and a bifunctional linear epoxy resin having a weight average molecular weight of 10,000 to 200,000 and having a hydroxyl group; and (B) a modified phenolic novolac having a phenolic hydroxyl group, at least part of which is esterified with a fatty acid. |
