PROBLEM TO BE SOLVED: To provide a side ditch block superior in sliding stop function and design without need of forming a form groove of an irregular pattern by improving strength of an upper face of the side ditch block. SOLUTION: In the side ditch block 2 having a pair of side walls 3a and an upper wall connecting the side walls, a reinforced cement thin plate 4 formed individually on the upper wall is provided. The pattern is formed on the surface of the reinforced cement thin plate 4. In addition, an irregular part 4c is formed on a rear face, and the irregular part is integrated to be buried in a block body. Thus, mechanical strength can be improved. In addition, wear of the pattern can be suppressed by using the reinforced cement thin plate excellent in wear resistance, and durability of the whole side block can be improved.
