PROBLEM TO BE SOLVED: To provide a surface-treated member made of a Ti alloy having excellent wear resistance and durability by improving the adhesion of a plating layer in a member made of a Ti alloy in which attention is payed to the wear resistance of a surface treatment layer, and to provide its production method. SOLUTION: An anodized coating having a coating thickness in the range of 0.1 to 10μm is formed on a Ti alloy base material using a phosphoric acid-sulfuric acid-based electrolytic solution under a treatment condition where voltage lies in the range of 100 to 300 V, and thereafter, Ni-based plating treatment such as Ni-P plating treatment is performed, thus the anodized coating is interposed between the Ti alloy base material and the Ni-based plating layer. In this way, the plating part permeates into the fine pores of the porous anodized coating, and, by the anchor effect, the peeling of the Ni-based plating layer is prevented, thus the member made of a Ti alloy having remarkably improved wear resistance can be realized.
