To provide a tennis court in the indoor-tennis court spread with a carpet, which is capable of easily helping replace parts of the carpet of the surface piles frequently used and prone to be abraded despite no formation of patchwork patterns.

The tennis court carpet for being spread on a tennis court is formed of not a conventional rolllike or sheetlike long carpet but a tile carpet. Before the surface piles of the carpet are abraded, the carpet parts of the surface piles frequently used and prone to be abraded and the carpet parts rarely used and hardly abraded are periodically exchanged and replaced according to a predetermined rotation, allowing the surface of the tile carpet on the whole tennis court to be satisfactorily maintained.
