To provide an anticorrosion rolling bearing having a low cost and a long life, capable of carrying out long-time stable and automatic supply of lubricating oil while suppressing the occurrence of rust even in a corrosive atmosphere such as water.
A lubricating oil containing a polymer 15 is filled in a space held between anticorrosion material outer and inner rings 11, 12. The lubricating oil containing the polymer is filled therein in a melted condition and quenched with pressure being applied thereto. The percentage of the polymer component in the lubricating oil containing polymer 15 is 10-50 mass%, and the rest is lubricating oil. The polymer component consists of low molecular weight polyethylene having an average molecular weight of 1×103 to 1×106 and a high molecular weight polyethylene having an average molecular weight 1×106 to 5×106, and the compounding ratio of the low molecular weight polyethylene to the high molecular weight polyethylene is in the range of 8:2 to 1:9.
