A sandwich structure includes a first ply of CFRP, a second ply of CFRP and a honeycomb or foam core. The first ply of the CFRP includes first carbon fibers and thermoset resin which is matrix reinforced with the first carbon fibers. The second ply of the CFRP includes second carbon fibers and thermoset resin which is matrix reinforced with the second carbon fibers. The core is sandwiched between the first and second plies of the CFRP. Ply thicknesses of the first and second plies of the CFRP are each not less than 0.05 mm and not more than 0.15 mm. The first thermoset resin is directly bonded to the core without interposing any other layer between the first thermoset resin and the core. The second thermoset resin is directly bonded to the core without interposing any other layer between the second thermoset resin and the core.
