PROBLEM TO BE SOLVED: To provide a molded article of an ultra-high-molecular-weight polyethylene having improved friction resistance and abrasion resistance and a method for producing the article. SOLUTION: The 1st invention comprises the bombardment of the surface of an ultra-high-molecular-weight polyethylene molded article with ions by an ion accelerator to carbonize the surface of the article to a depth of about 4μm and form a diamond-like carbon layer giving G band and D band by Raman spectroscopy and the 2nd invention comprises the ion bombardment with an ion accelerator at acceleration energy and ion exposure rate falling within respective specific ranges to obtain the surface-modified molded article of ultra-high-molecular-weight polyethylene.
