PROBLEM TO BE SOLVED: To provide a side ditch block capable of facilitating the location of blocks and easily manufacturing a boundary block. SOLUTION: The side ditch block is constituted by mounting the boundary block 10 along a boundary C on a side ditch block body 1 buried along the boundary C and, at the same time, forming a long ditch 2 in the longitudinal direction along the boundary C. The side ditch block body 1 uses one side of the long ditch 2 in the upper surface thereof for a boundary block mounting surface 5. Two projectional positioning sections 6 having a length shorter than that of the direction of the width of the mounting surface 5 are separately provided to the boundary block mounting surface 5 in the longitudinal direction, and the boundary block 10 has recessed positioned sections 12 engaged with the positioning sections 6 with a shape and size corresponding to positions corresponding to the positioning sections 6 on the lower surface thereof.
