PROBLEM TO BE SOLVED: To provide a lubrication grease for high temperature, having excellent durability at the high temperature, and produced at a reduced cost; and to provide a rolling bearing in which the lubrication grease is enclosed. SOLUTION: The lubrication grease for the high temperature is obtained by mixing a fluorine-based lubrication grease containing a perfluoropolyether oil as a base oil and a fluororesin powder as a thickener, with a urea-based lubrication grease containing a polyester oil as a base oil and an aliphatic urea compound as a thickener. The polyester oil is at least one kind selected from an aromatic ester compound between a 7-22C monohydric alcohol and an aromatic tri- or tetra-carboxylic acid or a derivative thereof, and an aliphatic ester compound between a 7-22C monobasic carboxylic acid, and trimethylol propane, pentaerythritol or dipentaerythritol.
