PROBLEM TO BE SOLVED: To construct a floor heating at a comparatively low cost, and obtain a sufficient heating performance by laminating a sheet heater on a heat insulating layer, and in addition, laminating tiles as a floor surface material on the sheet heater through a heat-spreading metal sheet. SOLUTION: A heat insulating panel (heat insulating layer) 16 comprising an organic expanded body such as a polypropylene expanded body is laminated on floor plates 15 as a floor base, and on the upper surface of the heat insulating panel 16, a sheet heater 18 is laminated, and on the upper surface of the sheet heater 18, tiles 24 are laid through a heat-spreading metal sheet, and a tile floor is organized. In this case, two sheets of the tiles 24 are connected and integrated by a heat-spreading metal sheet having a corresponding size on the rear surfaces of the tiles 24 to form a tile unit 28, and the tile 24 are laid on the sheet heater 18 under a configuration of the tile unit 28. The heat- spreading metal sheet performs a heat-spreading operation to transmit the heat from the sheet heater 18 to the tiles 24, and works as a backing material to impart a strength to the tiles 24. |
