PROBLEM TO BE SOLVED: To provide a snow melting device, by which the snow melting and freeze-proofness of a road surface in a cold district and in the winter are attained effectively while the safety of a walking and a traveling is improved and a comfortable road space, in which a flow water on the road surface is not generated, and an ecosystem and a river management are also considered. SOLUTION: In the large-sized plate block in which a heat generator for the snow melting and freeze-proofness of the road surface is buried in a section near to the upper section of the plate, a fluid flow path is installed in the thickness direction of the block, and a part or the whole of the component of the block is made of porous concrete and a permeable material.
