PROBLEM TO BE SOLVED: To provide a coating tool capable of smoothly applying a coating solution containing magnetic powders on the surface of a substrate moving relatively by using the coating tool and capable of preventing corrosion and wear of the end of the coating tool, by which the coating solution is uniformly applied for a long term. SOLUTION: In the coating tool used for coating a coating solution 12 on the surface of a substrate to be coated 1 which moves relatively, at least of the end part of the coating tool by which the coating solution is applied on the surface of the substrate to be coated comprises tungsten carbide as the hard phase and is composed of a cemented carbide comprising 3-25 wt.% of Ni as the binding phase with 5 oersted of coercivity and 10 gauss or less of saturated magnetic charge.
