To provide a unit tile which is excellent in adhesion between a building skelton and a tile, allows joint correction at the time of installation of the tile, and can reduce the manufacturing cost by decreasing the amount of resin to be used by solving the problem in the unit tile formed by connecting the conventional tiles.

This unit tile is characterized in that at the back and/or side of the tile, the tiles are connected by resin having a width and a thickness of 3 mm or less. The unit tile is characterized in that at the back and/or side of tiles, molded resin is thermocompression-bonded to connect the tiles. The unit tile is characterized in that the back and/or side of the tile is provided with a groove, and resin is embedded in the grooves to connect the tiles.
