To provide a partition concurrently served as a desk capable of being easily moved and re-allocated.

This partition concurrently served as the desk comprises, at least partly, a board having screw holes for fixing utilities, casters fixed to the lower part of the board, and a desk unit fixable to the board with the screw holes for fixing the utilities. Thus, since the casters are fixed to the lower part of the board, the entire part of the desk can be easily moved with the casters by raising the front side legs of the desk. After the desk is allocated at a specified position, the legs on the front side of the desk are put on a floor to fix the partition currently served as the desk on the floor. More desirably, the casters with rotation fixing devices (stopper) are used.
