PROBLEM TO BE SOLVED: To provide an insulated rolling bearing with excellent insulation properties capable of being manufactured at a low cost, capable of arranging an insulation layer with reduced processing man-hours and free from defect of a chamfer part. SOLUTION: This insulated rolling bearing comprises an inner ring 1, an outer ring 2, and a plurality of rolling elements 4 interposed between raceway surfaces of these inner and outer rings. The insulation layer 7 is formed on at least one of the inner peripheral surface 1a of the inner ring 1 and the outer peripheral surface 2a of the outer ring 2. The insulation layer 7 comprises at least a resin layer 7a formed on the at least one peripheral surface and a layer of a ceramics film 7b formed at a predetermined portion on the resin layer7a by an aerosol deposition method. The predetermined portion is a portion on an inner diameter surface of the inner ring 1 or on an outer diameter surface of the outer ring 2 in the resin layer 7a. COPYRIGHT: (C)2008,JPO&INPIT
