PROBLEM TO BE SOLVED: To provide a water-conveyance block for a drainage pavement, which has high strength and excellent drainage ability, and which makes a tire resistant to slip. SOLUTION: This water-conveyance block 1 for the drainage pavement is equipped with: a precast concrete block body 15 which is formed in such a manner that its cross-sectional height is greater in dimension than a thickness t of a drainage layer 9 of the drainage pavement and smaller in dimension than a depth d of an undersurface of an impermeable layer 10 of the drainage pavement; a downward opened groove-shaped water-conveyance passage 16 which is formed on the undersurface side of the block body 15 along the longitudinal direction of the block body 15; and a side drainage passage 18 which communicate with the passage 16 from a side surface 17 of the block body 15.
