(57) [Summary] [Object] To provide a resin sheet comprising an epoxy resin composition having excellent storage stability, a high molding rate, and excellent moldability. [Structure] A resin comprising an epoxy resin composition containing (a) an epoxy resin that is solid at room temperature, (b) an epoxy resin curing agent that is solid at room temperature, (c) a curing catalyst or a curing accelerator, and (d) a filler. It is a sheet. The epoxy resin composition does not cure alone and has first and second domains having different softening points of 75 ° C. or more and different compositions. The domains are in contact with each other adjacent to each other, and their interfaces are integrated by thermocompression bonding, and the overall shape is a sheet. |
