To provide a mini table, which is decomposable, storable, lightweight, and portable.

The mini table is constructed by assembling together top plate pieces 11 to 16 each having a rail structure, leg plates 41 and 42, connecting beams 31 and 32 each having grooves at both side surfaces thereof for slidably supporting the rail structures therein, and edge beams 21 and 22. The leg plates 41 and 42, the edge beams 21 and 22 and the connecting beams 31 and 32 can be folded into two, respectively. The leg plates 41 and 42 comprise swollen tip end parts, which horizontally extend with the same cross section, and L-shaped downward engaging structures at both longitudinal ends thereof, which structures project longitudinally and then orthogonally. In addition, the connecting beams 31 and 32 comprise through-grooves at two positions near both the ends thereof, into which grooves the tip end parts of the leg plates 41 and 42 are slidably inserted. Moreover, the edge beams 21 and 22 comprise through-holes which can engage with the L-shaped downward engaging structures of the leg plates 41 and 42 at two positions near the both ends thereof.
