To maintain preparation of a concrete retaining wall and prevent paint from peeling due to water and moisture by pigmenting the joint of the concrete retaining wall which is formed many divided surface with joints with color surface and making the divided surface with coated color surface.

In an L-shaped retaining wall block A (concrete retaining wall), the front surface of the upright portion 11 is made with a stone wall pattern surface 12 and a plurality of imitation stone-like divided surfaces 14 divided by joints 13 is formed on the stone wall pattern surface 12. The joints 13 run across the stone wall pattern surface 12 to divided the stone a wall pattern surface 12 deeper than stone-like divided surfaces 14. The joints 13 are pigmented by color development while the divided surface 14 are color painted. With the joints 13 pigmented by color development, entire surface of the stone wall pattern surface is not coated with paint. Therefore, perspiration of concrete may be maintained through the joints 13 part while the imitation stone-like divided surface 14 are color painted.
