A water-permeable sidewalk block using environment-friendly materials is provided to improve water permeability, to lower chlorosis phenomenon, to emit far infrared rays, to have soundproof effect, and to control humidity. A water-permeable sidewalk block using environment-friendly materials(10) comprises a base layer(11) contacted to the ground on which a sidewalk is installed, and a finish layer(13) joined to the outside of the base layer to manufacture the outside of the water-permeable sidewalk block smoothly and evenly. The base layer is manufactured by mixing coarse aggregate having the particle size of 5~10mm to permeate water smoothly, steel slag cement, water reducing agent and water and inputting in a rectangular mold, and then curing, and the finish layer is manufactured by mixing 1400kg/~1450kg fine aggregate having the particle size of 2.5~4mm, 450kg/~500kg binder, water reducing agent and water and inputting in a mold, and then curing in the appointed shape.
