Abstract
A method of producing a rolling sliding member, wherein, after a work for a rolling sliding member, which is made of a bearing steel and formed in a predetermined shape, is quenched, a heating start temperature is set to be 10 to 100° C., a heating finish temperature is set to be 220 to 350° C., a time between the heating finish time and the heating start time is set to be a heating time, the quenched work for the rolling sliding member is heated so that a rate of temperature increase indicated by the following formula becomes 7 to 35° C./srate of temperature increase=(heating finish temperature−heating start temperature)/heating time,
