Abstract: PROBLEM TO BE SOLVED: To provide an implant for an artificial joint that improves slidability under wet environment and can solve the trouble in which slidability when member subjects consisting of a resin and/or a metal such as an artificial joint are made to slide under wet environment in a biological tissue cannot be improved; and a production method of the same.SOLUTION: Diamond-like carbon (DLC) is a thin film that shows a low friction coefficient, however, a surface is hydrophobic, thereby a coefficient of friction same extent with that of the under air atmosphere is only shown under water lubrication. Air plasma treatment is performed and a surface is modified to be hydrophilic, thereby super low friction coefficient under water lubrication can be attained. This is applied to surface treatment of a slide member in a living matter such as an artificial joint.
