To prevent deformations such as a warpage, a swelling or a distortion from occurring by the radiation from a heat source in a counter board which keeps a space enabling the heat source such as a heat storage heating machine accompanying an upward outgoing radiation to be installed demarcated in the lower space.
This counter board 1 is used to form the space 101 in which the heat source 20 accompanying the upward outgoing radiation can be installed at the lower section. On the counter board main body 2 made of a woody plate, a nonflammable layer 3 consisting of a calcium silicate is integrally installed on the lower surface side. The nonflammable layer 3 is formed to have a thickness of at least 4 mm. Also, the external side of the nonflammable layer 3 is lined with a woody decorative veneer 6 to cover the nonflammable layer 3. Meanwhile, the external side of the woody decorative veneer 6 is coated urethane, and thus, the lower surface side of the counter board main body 2 is formed.
