To provide a heating tatami having the heating function in the tatami itself.

In this heating tatami, a tatami facing 2 such as rush, a heat convection protective layer 3, a plane-like heat generating body 4, a foam resin body 5, rice straw or an insulation board 6, and a back sheet 7 are in order laminated from the surface side. As for the heat convection protective layer 3, the layer which can protect the plane-like heat generating body 4 by elasticity of the material itself at receiving a shock or the like from the tatami facing side, and can transmit the heat of the plane-like heat generating body 4 to the tatami facing 2, is used.
