PROBLEM TO BE SOLVED: To enable a rack to be quickly dried after washing work. SOLUTION: An optical semiconductor layer 11 with the main component of titanium oxide on all over the surface including support pins 3 is formed on the body 2 of this rack made of synthetic resin. When the light from a fluorescent light equipped in a kitchen is irradiated onto the rack 1, a water film is formed on the surface of the rack body 2 by the function of exhibiting the hydrophilic property on the surface by optical excitation of the optical semiconductor layer 11 causing water drops not to be generated on the surface of the rack body 2 even after completion of washing and rinsing. Accordingly, the surface of the rack 1 taken out and a part of, dish in contact with the rack 1 come to be easily dried, and water drops are prevented from dropping from the rack 1 when the rack 1 is carried to a dish storage, place, or the like. Since titanium oxide exhibits an oxidation function, an antibacterial action to inhibit the growth of miscellaneous bacteria is manifested and so the surface of the rack 1 is kept clean to make it excellent in hygiene.
