When the on-surface heating element 7 generates heat, the heating panel 1a is warmed and expanded, and the gap between the male portion 63 and the female portion 65 of the core plywood 11 is filled. That is, the heating panel 1a absorbs the expansion of the plywood due to the heat of heating.

Next, as shown in FIG. 11, when the ends 61-3 of the heating panel 1a at the lower part in the longitudinal direction abut against each other, the female part 65 and the female part 65 are adjacent to each other. A connecting member 67 is provided between the female portions 65. The connecting member 67 is made of wood, rubber, or the like.

As described above, by using the heating panel 1 according to the embodiment of the present invention, the thermal efficiency is improved, and the efficiency of on-site construction such as electric construction and wiring construction is improved.
Since the heat insulating material 9 is built in, the heater efficiency is improved. In addition, by incorporating the soaking plate 5, temperature unevenness is reduced.

Further, by providing the cut-off portion 21 at the end of the heating panel 1, it is possible to cope with an irregular storage at the site.

Further, a male part 6 is provided at the end of the heating panel 1a.
3. By providing the female part 65, when the panel is laid, it is easy to lay the panel properly, the strength is improved, and the floor noise can be prevented.

In the above-described embodiment, the use as floor heating has been described. However, the present invention can also be used as wall heating. The method of using the heating panel 1 as a wall heater includes installation under a wall finishing material, unification with a ready-made wooden waist wall finishing material and the like, installation under a tile wall such as a bathroom, unit bath, and the like. It is integrated with wall materials and installed in places where heating is inadequate, such as corridors and halls.
