PURPOSE: A method for manufacturing rice cookers is provided to rapidly cook due to excellent heat conduction and to prevent scorched rice from being stuck. CONSTITUTION: A rice cooker comprises a rice cooking container, a pure gold inner surface layer, and a lid. The upper part of the rice cooking container of pure silver materials is opened and a space to accommodate the rice is formed. The pure gold inner surface layer is coated on the bottom and inner wall surface of the rice cooking container. The lid is covers the opening part of the rice cooking container. A method for manufacturing the rice cooker comprises the following steps: manufacturing the rice cooking container of pure silver materials and forming a pure silver inner surface layer. The step of manufacturing the rice cooking container of pure silver materials comprises the following steps: cutting a pure silver plate (S101), drawing a concentric circle (S102), striking a part while the predetermined length of edge valley is left to the outside (S103), evenly spreading wrinkles of the end part by a wood hammer (S104), and performing the annealing (S105).
