PROBLEM TO BE SOLVED: To obtain the subject composition which can make a cured product excellent in heat resistance and useful for epoxy resin-based laminates, coating materials and the like by including a specific alkoxy group-containing silane- modified epoxy resin and a curing agent for epoxy resins. SOLUTION: This composition is obtained by including (A) an alkoxy group- containing silane-modified epoxy resin obtained by conducting alcohol elimination condensation reaction between (i) a bisphenol type epoxy resin preferably comprising bisphenol A type epoxy resin and (ii) a hydrolyzable alkoxysilane preferably comprising a poly(tetramethoxysilane) of the formula (Me is methyl; n is >=0 and the number n of recurring unit(s) is 1 to 7 on average) in the weight ratio of silica equivalent weight of the component ii to the weight of the component i of preferably 0.01 to 3 and (B) a curing agent for epoxy resins preferably comprising a polyamine-based curing agent, in the equivalent ratio of the function group having active hydrogen in the component B to the epoxy group in the component A of preferably around 0.2 to 1.5.
