Beschreibung
Zusammenfassung:	The present invention provides an epoxy resin composition comprising a (A) component, which is an epoxy resin having a mesogen skeleton, a (B) component, which is a curing agent containing a novolac resin prepared from a bivalent phenol compound, and a (C) component, which is an inorganic filler, a content of a monomer contained in the curing agent of the (B) component during a semi-hardened state (a B-stage) thereof being 0.6 mass % or less with respect to a total resin content. The present invention also provides a semi-hardened epoxy resin composition, a resin sheet and a prepreg.
