PROBLEM TO BE SOLVED: To obtain a silicone-modified epoxy resin using bisphenol-A or bisphenol-F as a base, having a high heat resistance and useful as a coating capable of being applied to a heating tool such as an oven. SOLUTION: This silicone-modified epoxy resin of formula I (Ep expresses Me or a group of formula II) is obtained by heating and melting an epoxy resin based on general bisphenol-A or bisphenol-F at 50-150 deg.C, adding 5-50 wt.% methoxy group silicone intermediate based on the total weight of the reacting material and heating at 150-200 deg.C. It is preferable that the density of the methoxy group silicone intermediate is 1,120-1,140, its viscosity is 50-100 cp (at 25 deg.C), and methoxy content is 14.0 to 16.0.
