Abstract
There is provided an epoxy resin composition containing an epoxy compound, which has a low viscosity and a low dielectric constant, and when added to a general-purpose epoxy resin composition, can lower a viscosity of the composition and can sufficiently lower a dielectric constant of an epoxy resin cured product obtained from the composition. An epoxy resin composition comprising: (a) an epoxy component containing at least an epoxy compound of formula [1]; and (b) a curing agent: wherein Rto Reach independently are a hydrogen atom or methyl group, and Lto Leach independently are pentamethylene group, hexamethylene group or heptamethylene group.
