Abstract
In the slide member, a recessed and projected pattern is formed in a slide surface of a mother member of the slide member allowed to slide in contact with a mating member, recessed portions of the recessed and projected pattern are filled with a lubricant, and the area ratio of the recessed portions is set in a range of 30 to 70% while the depth thereof is set for 10 .mu.m or less. The slide member is able to secure the lubricating property, wear resisting property and seize-up resisting property of the slide surface thereof with the recessed and projected pattern formed therein for a long period.
