Claim:
1. A modified epoxy resin composition, comprising: a component (A) which is a mixture of compounds resulting from replacement of one glycidyl group, two glycidyl groups, and three glycidyl groups of α-type tris-(2,3-epoxypropyl)-isocyanurate with a melting point of from 98 to 107° C. with a functional group represented by formula (1) and prepared by adding acid anhydrides of formula (2): wherein each of R a compound (B) which is an α-type tris-(2,3-epoxypropyl-isocyanurate with a melting point of from 98 to 107° C.; wherein a molar ratio of the component (A) to the compound (B) is from 3.33/1 to 2/3 the modified epoxy resin composition is a liquid which is stable for at least 50 days at room temperature, a total number of glycidyl groups per molecule in component (A) and compound (B) is at least two on average of a total number of (A) and (B) molecules.
