PROBLEM TO BE SOLVED: To provide a high-molecular weight epoxy resin excellent in flexibility, heat resistance, low water absorbency, electrical characteristics and moldability, a composition for an electrical laminate, and an electrical laminate. SOLUTION: The high-molecular weight epoxy resin is represented by general formula (1) äwherein A is a chemical structure represented by general formula (2) or (3), with the A of general formula (3) accounting for at least 5 mol% of the epoxy resin of general formula (1); B is H or a group represented by general formula (4); and n is 25 to 500 on average} and has a weight-average molecular weight of 10,000 to 200,000.
