PROBLEM TO BE SOLVED: To enhance execution precision regardless of a degree of skill of a skilled worker by horizontally and vertically providing joining projections on the base body of a tile. SOLUTION: The height of a previously designated joint width 6 is provided on the arbitrarily vertical and horizontal parts of a tile base body 1, and joining projections 2, 3, for instance, having 1/2-2/3 thickness of the thickness of the tile base body 1 are provided. Twisting or the like is developed on the arbitrary part of the building frame surface executing the tile base body 1 to be made horizontal and vertical lines, the terminal of the tile base body 1 is matched thereto to join the joining projection of the adjacent tile base body 1. Thereby the execution of the joint width 6 of automatically uniform high precision and the execution of horizontal and vertical joints 7 can be performed. Furthermore, a reflection body metal net reflecting an electromagnetic wave is inserted in the inside of the tile base body 1 and molding and baking are performed, so that electromagnetic damage can be also prevented.
