To provide a sectional desk capable of raising strength in a finished product though the desk is easily assembled with a simple structure, reducing a cost by standardizing main configuration components, and coping with even the case that the interval of leg bodies is changed due to a difference in desk configuration, by adding the minimum component.

The sectional desk includes: end leg bodies 3; a middle leg body; top boards 1 (2); kneehole panels 6; T shape fixtures 12; cross shape fixtures; and beams 9. The kneehole panels 6 are connected between the rear end surfaces of the respective leg bodies. The T shape fixtures are connected to the middle part in a front and rear direction of the upper end parts of the end leg bodies and each connection part is arranged to face inward. The cross shape fixtures are connected to the middle part in the front and rear direction of the upper end part of the middle leg body and both the connection parts are arranged to face rightward and leftward. The respective end parts of the beams are connected to both the opposing connection parts so as to connect the adjacent leg bodies with the use of the kneehole panels and the beams. The top boards are screwed onto the front ends of the end leg bodies and middle leg body, and the beams.
