An annular sliding member which is used in a mechanical seal, is attached to a rotating shaft, and slidably comes into contact, by being applied with energizing force in the axial direction, with another annular sliding member attached to a housing, wherein the sliding surface which comes into contact with the other sliding member is formed from: a dynamic pressure generating groove which guides a fluid to be sealed from a region to be sealed to the side of a region to not be sealed of the sliding surface, and a concave-convex section configured from a plurality of minute grooves which have a shallower depth than the dynamic pressure generating groove.
