Abstract
Disclosed is an encapsulation epoxy resin material containing an epoxy resin (A) and a curing agent (B). The epoxy resin (A) contains a compound represented by the general formula (I) below. The encapsulation epoxy resin material has excellent reliability in flame retardance, formability, reflow resistance, moisture resistance, high-temperature shelf characteristics and the like, and is suitably used for encapsulation of a VLSI. Also disclosed is an electronic component comprising an element encapsulated with such a material. (I) (In the general formula (I), Rs may be the same or different and respectively represent one selected from substituted or unsubstituted hydrocarbon groups having 1-12 carbon atoms and substituted or unsubstituted alkoxy groups having 1-12 carbon atoms; n represents an integer of 0-4; Rs may be the same or different and respectively represent one selected from substituted or unsubstituted hydrocarbon groups having 1-12 carbon atoms and substituted or unsubstituted alkoxy groups having 1-12 carbon atoms; and m represents an integer of 0-6.)
