摘要：
An epoxy resin composition is provided that mainly comprises an epoxy resin, a curing agent, and an inorganic filler, and that cures into a product having a coefficient of water diffusion of up to 1.times.10.sup.-4 cm.sup.2 /hr. at a thickness of 3 mm under humid conditions at 85.degree. C. and RH 85%, wherein 1-50% by weight of an inorganic water absorbing agent such as molecular sieve, silica gel and porous silica is added to the epoxy resin composition. The composition offers cured products having fully low moisture permeability and is thus suitable as a pre-molded hollow package-forming material.
