Abstract
The present invention provides a novel cyanate ester compound which has excellent solvent solubility and from which a hardened product having a low coefficiency of thermal expansion and excellent flame retardancy and heat resistance is obtained. The present invention is a cyanate ester compound obtained by cyanating a naphthol-dihydroxynaphthalene aralkyl resin or a dihydroxynaphthalene aralkyl resin.
