BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating base material made of synthetic resin foam which is used as a roof base material, a wall base material and the like.

[0002]

2. Description of the Related Art Conventionally, a heat insulating base material made of a foamed synthetic resin formed in a flat plate shape has been widely used as a roof base material or a wall base material. As an example, the heat insulating base material is laid on the base plate, tile tiles are placed on the heat insulating base material at intervals of tiles, and the tile tiles are nailed to the base plate through the heat insulating base material. It was fixed, and the roof tiles were locked on each roof tile and thatched.

[0003]

However, according to such a conventional heat insulating substrate, since the roof tiles are nailed to the base plate through the compressible and soft heat insulating substrate,
The roof tile is placed on a heat-insulating base material and nailed in a state of floating from the base plate, so that the roof tile is not sufficiently fixed to the base plate and is hit on the base plate under strong wind. There was a problem that the nails would come off, the roof tiles would be unfixed, and the roof tiles might scatter. The problem of such a heat insulating base material also occurs when it is used as a wall base material.

An object of the present invention is to provide a heat-insulating base material capable of sufficiently fixing the member placed thereon. Another object of the present invention is to provide a heat insulating base material that can easily determine the position of a member placed thereon. Another object of the present invention is to provide a heat insulating base material which can be arranged without leaving a gap between adjacent ones. Another object of the present invention is to
