<p><P>PROBLEM TO BE SOLVED: To provide a lightweight tile having practically sufficient strength. <P>SOLUTION: The lightweight tile 2 is formed with a plurality of recessed parts 6 recessed in plate shape, on one face of an impermeable tile body 4, and a non-recessed part 12 surrounding the recessed parts 6 is formed in grated shape. Each recessed part 6 can be filled with a porous body. The porous body can include filling pieces and a binder for connecting the filling pieces to one another, and the filling piece can be formed of a porous material. A method for manufacturing the lightweight tile 2 comprises preparing the tile body 4 formed with the plurality of recessed parts 6 recessed in plate shape, at a part of the one face, and filling each recessed part 6 with a mixture containing the filling pieces and a binder before hardening, and solidifying it. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
