That is, when the pipe is embedded inside the heat conductive plate, the pipe is supported in a state of being floated above the surface of the heat insulating plate such as Styrofoam during mortar casting and curing. It is necessary, and it takes a lot of work to make. Further, when the tubular body is fitted into the groove portion of the heat insulating plate body and sandwiched between the two plate body bodies, the tube body support at the time of manufacture is easier than the above case, but The contact area with the tubular body fitted in the groove without a gap is large, and the contact area between the heat conductive plate and the tubular body is small, so that the heat conduction to the heat conductive plate is not always sufficient. Has not been done to. Therefore, workability during manufacture and thermal loss during use are not always sufficient.

The present invention has been made in view of such circumstances, and provides a building board that is easy to manufacture, can effectively utilize heat during use, and can achieve improvement in both technical and economic aspects. The purpose is to do.

<Means for Solving the Problem> The present invention provides a heat conductive plate-like body made of a heat conductive material that is cured to form a board surface and a heat conductive plate-like body having a groove on the joint surface.
