PROBLEM TO BE SOLVED: To provide an anticorrosive sliding member capable of ensuring the performance of lubrication, anticorrosion and anti-seizure of a sliding face of an uneven pattern for a long period. SOLUTION: In an sliding member that supports the rotating or swinging object applied to a plain bearing, an inside outer ring race face of rolling bearing and a contact part of thrust receiving part or an artificial joint of groove bearing, an uneven pattern is formed to the sliding face of base metal with 0.8 to 1.6 mm arrangement pitch of recessed or convex part and 1μm to 10μm depth on 30 to 70% of whole sliding face. Furthermore the anticorrosive sliding member filled by solid lubrication film in the recessed part of this hard film surface is provided, arranging the hard film of TiN, TiC, TiB2 , etc., or the hard film by ion implantation with the thickness capable of maintaining the uneven face of the uneven pattern along with the formation of the uneven pattern of the base metal.
