PROBLEM TO BE SOLVED: To provide a pavement stone block with easy laying work and a novel shape hardly deviating once it is laid. SOLUTION: A rectangular base (a block body 1) is formed by a roof tile like sintered body with an appropriate thickness. Recessed parts 2 symmetrical to a longitudinal center line (a) and a horizontal center line b with wider inner sides than opening sides are formed on longitudinal rims as seen from above, and inner edges 3 of the recessed parts are parallel with the longitudinal center line. A recessed part shape and a block part shape (a connecting part 4 shape) within a range enclosed by the horizontal center line and an inner edge extension are shaped with a relation of the front and back.
