PROBLEM TO BE SOLVED: To use a panel by laying on a floor such as flooring of an existing house, without spoiling the basic tone of the floor of a room, and to prevent the formation of projecting warps and cracks in the width direction of continuous woody pieces that are connected windably, not only having excellent executability. SOLUTION: A mat-type woody floor heating panel has a constitution in which a plurality of continuous woody pieces 2, 2 that are juxtaposed are connected windably by a flexible rear face material 3, and in which a conduit 6 for heating fluid or a heat generating wire are buried in a recessed groove 5 for burying that is formed at the roughly center of the rear of the continuous woody pieces 2. Both right and left end face portions in the width direction of each continuous woody piece 2 and 2 are provided with a male side recess and projection part X at one side, and a female side recess and projection part Y at the other side, respectively. The continuous woody pieces 2, 2 that are adjacent to each other have a construction, in which they are fitted to each other with a recess and projection relationship in the presence of an opening by these male and female side recess projection parts X and Y. Moreover, the openings T1 and T2 between the male side recess and projection part X and the female side recess and projection part Y that are fitted with the recess and projection relationship are set larger at the central part than the upper and lower parts. |
