PROBLEM TO BE SOLVED: To provide a security panel equipped with such a structure that the surface side and the reverse side of a shell are thermally insulated in the security panel coating a core material having heat resistance or fracture resistance the like with the shell of a metal plate such as a steel plate or the like. SOLUTION: In the security panel SP coating the core material Cm having heat resistance, fracture resistance with the metal plate-made shells 2 and 3, the shells 2 and 3 of the security panel SP form the surface sides and the reverse sides of them into separation structures in the circumferential side of the panel and, at the same time, the separation structure parts are combined with each other by laying a heat insulation member 4c or 5c preventing heat bridge between both of them.
