PROBLEM TO BE SOLVED: To provide a heat radiation structure capable of efficiently reducing heat transmitted from a baking furnace to a control device, and of properly keeping reliability and a service life of the control device, in a ceramic art kiln provided with a control device between a ceramic art kiln and an armoring cover covering the ceramic art kiln. SOLUTION: This heat radiation structure is provided with: the baking furnace 2; armoring members 4 and 5 covering the baking furnace 2; a heater control circuit part 15 arranged between the baking furnace 2 and the armoring members 4 and 5 for controlling the temperature in the baking furnace 2; and a support member 25 having one end 2 connected to the armoring member 4 covering the bottom surface of the baking furnace 2 and erected from the connection part thereof to support the heater control circuit part 15. Graphite sheets 30, 31 and 32 each made by baking and graphitizing a polymer film are attached to the support member 25 from the mounting part of the heater control circuit part 15 to the armoring member 4 covering the bottom surface of the baking furnace 2 along its surface.
