To provide a tennis court in which, in a conventional tennis court, only conventional singles and doubles matches can be played and two players cannot practice a game simulating a doubles match man to man but, in the present invention, such a match-style practice can be performed.

An additional line dividing the inside of a court to right and left is drawn, and areas of duce-side and advantage-side crosscourts inside of the court are made clear. Consequently two players can practice a match-style game simulating doubles plays by competing over for the shot point in the crosscourts while using only the crosscourts man to man.
