1. A sliding member, comprising:
a first sliding portion that has a first friction sliding mechanism having at least two first parts and that has a first lubricant placed between the first parts; and
a second sliding portion that has a second friction sliding mechanism having at least two second parts and that has a second lubricant placed between the second parts, wherein:
the first sliding portion has a lubricant feed port from which the first lubricant is fed;
the second sliding portion has no lubricant feed port from which the second lubricant is fed;
the first lubricant contains first base oil and a first additive;
the second lubricant contains second base oil and a second additive containing conductive carbon; and
the second lubricant contains a relatively larger amount of the conductive carbon than the first lubricant;
wherein the first lubricant contains 0.01 to 15 mass % of the conductive carbon based on total mass of the first lubricant.
