PURPOSE: An epoxy resin composition is provided to have excellent flame retardance without using a flame retardant, and to have excellent flexability, adhesion, and reliability. CONSTITUTION: An epoxy resin composition comprises 2-15 weight% of an epoxy resin, 0.5-12 weight% of curing agent, 0.01-2 weight% of a curing accelerator, and 70-95 weight% of inorganic filler. As the epoxy resin, aromatic hydrocarbon formaldehyde resin-modified novolak type epoxy resin in chemical formula 1. In chemical formula 1, R1 and R2 is respectively and independently a C1-4 linear or branched alkyl group, the average K value is 0-2, and the average l value is 1-9. |
