Abstract: The present invention relates to a novel epoxy resin having improved heat-resistance, thermal expansion properties and processability, and to a thermosetting resin composition comprising the same. To this end, the present invention provides an epoxy resin of Chemical Formula 1 as disclosed in the Description, an epoxy resin composition comprising the same, and a packaging, substrate and transistor formed thereof. When a composition that contains an epoxy resin with a specific side functional group according to the present invention and/or an epoxy resin with a specific core structure is cured, a filler forms a strong chemical bond with the epoxy resin, thereby maximizing filling effects of the filler for the epoxy resin. Moreover, with the specific core structure, heat resistance and heat expansion properties of a cured product are substantially improved (CTE is reduced), and enhanced glass transition properties, strength and processability are demonstrated.
