To prevent increase of man-hours and material cost in a machining process of casting molding by drilling a hole in a part of a wall-mounting portion of a wall-mounted urinal.

A wall-mounted urinal mounted to a mounting tool 3 comprises a wall-mounting portion 1 and a hole portion 2. There is dog-legged structure over the hole portion 2 in the wall-mounting portion 1. A casting molding of the urinal having the wall-mounting portion employs a back die 5 and a front die for molding a mounting surface to a hanger portion or a wall, adheres a non-water-absorbing material such as a wood plate to an opening position of a hole of the back die 5, and prevents slurry from adhering to the part in the casting-molding process. After removing the dies, the hole portion 2 is drilled. Thus, the casting-molding is allowed without using a split mold. It is be molded with a die, the die is removed, and then the hole portion 2 may be cut by a cutter or a gauge. Therefore, increase of man-hours and material cost can be prevented in the machining process of the casting molding.
