PROBLEM TO BE SOLVED: To provide a design structure of a concrete retaining wall in which differences of colors and values are formed among imitation stonelike division faces to obtain abundant design patterns and efflorescence is hardly brought and further, even if it is brought, it is made inconspicuous to reduce dirty marks caused by the efflorescence. SOLUTION: A wall face 2 is divided into several imitation stone-like partition faces 4 by joints 3, in a design structure of a concrete retaining wall. Several imitation stone-like partition faces 4 are formed of heat-absorbing partition faces 41 colored by a color pigment having a lower light-reflectivity than a concrete surface color, heat-reflecting partition faces 42 colored by a color pigment having a higher light-reflectivity than the concrete surface color, and the concrete surface partition faces 43.
