PURPOSE: A prefabricated shelf is provided to assemble and disassemble simply by minimizing the number of bolt joints and to have enough fixing strength at an assembled state. CONSTITUTION: A prefabricated shelf comprises a rectangular panel having four semicircular grooves(11,12,13,14) respectively to rectangular corners one by one and two pairs of posts(20,21,22,23) connected by ten tension rods respectively, wherein the two posts(21,23) from different pairs are connected by intersecting two tension rods(24,25) and the tension rods(24,25) connecting two posts(21,23) from different pairs are fixed to the posts(21,23) by bolts and nuts and the grooves of the panel are fixed to the posts when assembling.
