PURPOSE: A manufacturing method of an accessory is provided to make shape of accessory different from each other. CONSTITUTION: A manufacturing method of an accessory comprises a step of preparing alloy by mixing and melting 77-87 wt% of silver powder and 23-13 wt% of copper powder; a step of forming a thin plate by rolling and forging the alloy; a step of applying heat of 780-800 °C until the time the thin plate is melted; a step of forming a large wrinkle according to preset patterns, and forming small wrinkles near the large wrinkle; a step of increasing the size of large wrinkle and small wrinkle, and additionally forming new small wrinkles near the small wrinkle; a step of removing impurities by acid treating the thin plate; a step of cutting the thin film to a predetermined size; and a step of post-treating the thin film.
