PROBLEM TO BE SOLVED: To provide a cooling panel for furnace wall of a blast furnace which is easily manufactured at lighter weight and lower cost in comparison with a stave cooler and unnecessary to weld on a coolant path extremely low danger to water leakage and low pressure loss of the cooling water, and does not cause the stagnation of water, and can omit and expandable tube and shorten the length of piping passing the coolant, in the cooling device for furnace wall used for cooling the furnace wall, etc., in the blast furnace. SOLUTION: In the cooling panel for furnace wall peripherally arranged on the inner surface of the furnace wall in the blast furnace, the copper or copper alloy-made coolant piping 2 passing the coolant, are disposed, and inserted into cut-off parts cut off so as to match to the coolant piping 2 in a copper or copper alloy-made plate 1 and the jointing lines with the plate, are welded. In the coolant panel, ribs 3, 4 for reinforcing, are arranged.
