Abstract
One object of the present invention is to provide a blade for forming ribs that is able to improve wear resistance; in order to achieve the object, the present invention provide a blade for forming ribs that forms ribs either on the surface of a substrate or via an undercoating layer on the surface of a substrate by moving a blade body in a fixed direction relative to a paste film in the state in which comb teeth formed on at least a portion of the periphery of said blade body are penetrated into said paste film formed on the surface of said substrate to plasticly deform said paste film; wherein, the surface of said comb teeth formed on said blade body that makes contact with said paste film is coated with a compound layer in which hard particles are dispersed in a metal.
