To provide a directly sticking floor heating floor material superior in sound insulating performance, providable in a simple manufacturing procedure, and without causing nonuniformity of the temperature on a surface, as the electric heater type directly sticking floor heating floor material.
This directly sticking floor heating floor material 10 has a woody floor base material 11, an electric heater integrally incorporated into the woody floor base material 11, connectors 17 and 18 connected to the electric heater, and a sound insulating sheet 21 stuck to a reverse surface of the woody floor base material 11. A large number of sound insulating grooves 14 and electric heater storage recessed grooves 15 are formed on the reverse surface of the woody floor base material 11. A thermosensitive heating wire A having a positive temperature coefficient characteristic (a PTC characteristic) is also used as the electric heater, and the thermosensitive heating wire A is integrated into the woody floor base material 11 in a state of being embedded in the electric heater storage recessed grooves 15 for storing a heating element formed on the reverse surface of the woody floor base material 11.
