PROBLEM TO BE SOLVED: To provide a holder for a rolling bearing capable of improving durability and preventing early separation of a plating layer.SOLUTION: A holder for a rolling bearing having a sliver plating layer on its surface and made of a ferrous metal material is provided with a base plating layer comprising, for example, copper plating that is formed on the surface of the ferrous metal material and whose surface is formed smoothly; and prevents early separation of the plating layer as a holder for a rolling bearing provided with the silver plating layer so as to directly closely contact on the base plating layer without any gap by using a rack electric plating method. |
