Abstract:
1. A granular epoxy resin composition for encapsulating a semiconductor element used for a semiconductor device obtained by encapsulating the semiconductor element by compression molding, wherein, in a particle size distribution of said granular epoxy resin composition as determined by sieving said granular epoxy resin composition for encapsulating the semiconductor element using JIS standard sieves, a ratio of particles to said granular epoxy resin composition total having a size of 2 mm or greater is not more than 3% by mass, a ratio of particles to said granular epoxy resin composition total having a size of 1 mm or greater, but less than 2 mm is from 0.5% or more by mass to 60% or less by mass, and a ratio of microfine particles to said granular epoxy resin composition total having a size of less than 106 μm is not more than 5% by mass.
