PROBLEM TO BE SOLVED: To provide concrete pavement capable of suppressing a rise of road surface temperature under a burning sun in the summer. SOLUTION: This concrete pavement has a non-water permeation layer 2 constructed on a subbase course 3, a porous concrete layer 1 constructed on the non-water permeation layer 2 and having a continuous void ratis of 20 to 30%, and a water drain port 4 for preventing an amount of water exceeding water collection capacity of the porous concrete layer 1 from flowing out onto an upper face of the porous concrete layer to collect water in the porous concrete layer 1.
