PURPOSE: To produce a decorative sheet colored into various color tones by forming a sprayed coating film on a substrate by the use of plural pieces of wire containing Al and Ti and then anodizing this sprayed coating film. CONSTITUTION: A sprayed coating film is obtained by thermally spraying a metal onto a substrate consisting of inorganic material or organic high polymer material. The thermally spraying metal is at least either of Ti and Al, and plural pieces of wire of this metal is simultaneously melted and sprayed. Subsequently, this sprayed coating film is anodized to form an anodic oxidation film. It is preferable to apply shot peening to the sprayed coating film after thermal spraying. At the time of thermal spraying, the thickness of the Al wire can be different from that of the Ti wire. Because plural pieces of the metallic wire are melted, thermally sprayed grains are increased in size and the mechanical joining strength among mutual grains can be increased. The anodic oxidation film is colored by an electrolytic pigmenting method or a dyeing method.
