An epoxy resin composition which comprises: (a) an epoxy resin having at least two epoxy groups in the molecule, (b) an epoxy resin curing agent, (c) a cure accelerator, (d) an aromatic polyamide pulp and (e) an inorganic filler as the essential components, the aromatic polyamide pulp (d) being contained in an amount of 0.5 to 10% by weight based on the total weight of the component (a), the component (b) and the component (d), and the inorganic filler (e) being contained in an amount of 75 to 94% by weight based on the total weight of the component (a), the component (b), the component (c) and the component (e), and a semiconductor device sealed with the above epoxy resin composition. The cured product of the epoxy resin composition is good in balance of hot impact strength and hot flexural strength and hence, the semiconductor device sealed with the epoxy resin composition is excellent in soldering resistance.
