PURPOSE: An inner pot for an electric rice cooker, and a manufacturing method thereof are provided to improve durability by preventing a coating layer from being exfoliated. CONSTITUTION: A manufacturing method of an inner pot for an electric rice cooker is as follows: A stainless steel inner pot is prepared(S10). The inner pot is preprocessed to form a copper plating coating layer(S20). The copper plating coating layer is formed on the outer surface of the preprocessed inner pot(S30). A plasma coating layer is formed on the outer surface of the copper plating coating layer(S40). A ceramic coating layer is formed on the outer surface of the plasma coating layer(S50). A clear coating layer is formed to protect the copper plating coating layer(S60). |
