The heater unit 11 includes the heater wire 3, heat equalizing materials 26 and 9 sandwiching the heater wire 3 above and below, and a heat insulating material 10 provided below the heat equalizing material 9.

[0005] FIG. 15 shows a conventional wooden heating floor material for a general household with a wooden bottom plate removed. As shown in FIG. 15, a frame 2 is provided on the back side peripheral edge of a wooden surface material 1 constituting a panel-shaped wooden heating floor material 50, and a heater wire 3, a heater power line 4, A connector 51 and a connector lead wire 52 are provided. The heater wire 3 is
One end of the heater power supply line 4 is connected, and the other end of the heater power supply line 4 is connected to a connector lead wire 52 via a connector 51.

[0004] At both ends of the back surface in the longitudinal direction of the wooden surface material 1,
A wiring storage section 33 of a certain space surrounded by a wooden frame is provided. The power supply line 4 for the heater, the connector 51, and the lead wire 52 for the connector are stored in the wiring storage section 33. The connector lead wire 52 supplies power to the heater wire 3 and also connects the heater wire 3 between each panel-like wooden flooring material.
The connector housing 52 is also used as a lead wire for connecting the connector lead wire 52 so that the connector lead wire 52 can be freely housed and wired from any direction of a cable outlet 53 provided horizontally, above, or below. Has a large space.

[0005] The connector lead wires 52 are subjected to terminal treatment for each single wire, and crimp terminals (not shown) are attached to the ends thereof, and these are connected by male and female fitting.

[0006]

However, according to the conventional wooden heating floor material 50, the wooden bottom plate 5 is provided under the heater unit 11, so that the thickness becomes large as a whole, and handling becomes inconvenient. There was a problem.

[0007] Further, if the rear floor material 5 is removed to make the wooden heating floor material 50 thinner, moisture tends to be easily received from under the floor, so that the wooden part is corroded and the life is shortened. .

Further, since the cable outlet 53, which is the insertion portion of the connector lead wire 52, is formed on the back surface of the wooden surface material 1, especially when the wooden heating floor material 50 is thinned, the wooden heating floor material is reduced. When connecting the member 50, the cable outlet 53 is difficult to see because the cable outlet 53 is difficult to see, and if the connector lead wire 52 is lengthened to facilitate the connection operation, the connector lead wire 52 will be connected.
