Abstract
A novel epoxy compound having a chemical structure in which an aromatic ring having a glycidyl raedical attached thereto has a tertiary alkyl radical at its ortho or meta-position. An epoxy resin composition comprising the epoxy compound, a curing agent, and a curing accelerator which cures into a product having a low dielectric constant.
