PROBLEM TO BE SOLVED: To efficiently emit heat generated in a high heating apparatus by adhering an artificial isotropic laminate, as a heat sink, which has thermal conductivity higher than a specific value and has high thermal conductivity carbon fiber as reinforcements, to a sandwich panel that has complex material having carbon fiber as reinforcements as a surface skin material. SOLUTION: This sandwich panel comprises an aluminum honey-comb core 2, an adhesive 3 of a surface skin material 7 with the aluminum honey-comb core 2, the surface skin material 7 made of complex material having carbon fiber as reinforcements, a heat sink 9 that is mounted with a high heating apparatus 5 and is formed from an artificial isotropic laminate having carbon fiber as reinforcements, and an adhesive 10 of the heat sink 9 and the surface skin material 7. By using high thermal conductivity carbon fiber whose thermal conductivity is higher than 600 W/m.k, isotropically laminated laminate is substantially equal to that of aluminum alloy. Since coefficient of thermal expansion of this heat sink 9 is close to coefficient of thermal expansion of the surface skin material 7, stress by the thermal expansion hardly occurs and construction adhesive with high strength can be used.
