PURPOSE:To be able to suppress the destruction of a heat source with a sharp knife etc. and also prevent the generation of a warp due to heat expansion and swelling accompanying humidity by constituting heating floor in such a way that a base material is attached n the bottom surface of a metal plate having a heat source through a such ion layer possible to absorb shear stress and on the top surface of the metal plate a wood floor material is attached through a cushion layer having the same property as before. CONSTITUTION:A steel plate 6 having a heat source 1 is adhered to polywood 7 as a example of a base material 4 with adhesive agent such as epoxy resin through a cushion layer 3. A wood floor material 5 is adhered to the top surface of the steel plate 6 having the heat source 1 through a cushion layer 3. The cushion layers have sufficient thickness and flexibility capable of absorbing shear stress based on elongation due to expansion of the plate 2 and swelling of the wood material 5 and the base material 4. As for the cushion layers 3, very flexible resin such as silicon or urethane, or polystyrene, or polyolefin-based foam materials are used and they should have high heat resistant property because they contact the heat source 1.
