To provide an assembly structure which is easy to be assembled and can be disassembled, stored, or carried, when it becomes temporarily unnecessary, and an assembly kit used for assembling the assembly structure.

The assembly kit consists of a first unit, which is a flat plate, a second unit, which is provided by joining 2 flat plates together at the edges so that it has horizontal and vertical planes, a third unit, which is provided by joining 3 flat plates at their appropriate edges so that it has 3 different dimensions, and a trough-shaped unit, which is provided by forming a plate into a trough shape. These units are assembled together as needed, to make an assembly structure. The above units have a loop area for joining other units, at least at one edge along the rim. The assembly kit features the function that adjacent units can be joined together by inserting a stick-like connector through the loops of one unit and the loops of an adjacent unit. The assembly structure is formed in three-dimension using plurality of the above assembly kit, with adjacent units joined together as described above.
