PROBLEM TO BE SOLVED: To provide a highly flexible resin that can be used for materials for electrical and electronic fields, adhesives, etc., capable of giving a cured product having an excellent balance of adhesiveness, flexibility, and electrical characteristics, and its high possibility A flexible resin cured product is provided. A difunctional aliphatic having a diglycidyl purity of 90% by mass or more and total chlorine of 0.3% by mass or less obtained by distillation purification of a reaction product of a dihydric alcohol having 2 to 12 carbon atoms and an epihalohydrin. A highly flexible resin having a number average molecular weight of 300 to 100,000, obtained by reacting an epoxy compound (X) with a divalent phenol compound (Y) in the presence of a catalyst. A curable resin composition containing the highly flexible resin and a cured product of the curable resin composition. [Selection figure] None |
