PURPOSE: An inner vessel for an electric cooker is provided to reduce the fuel cost, to improve the taste of foods and to enhance the endurance against an impact by inserting a ferromagnetic member into the electric cooker. CONSTITUTION: An internal vessel(90) is accommodated in an electric cooker. A plurality of protrusions(50) are formed in the internal vessel(90). Internal stuff(60) is coated on a non-metallic vessel(70) by a predetermined thickness. The internal stuff(60) is inserted into the protrusions(50) and fixed thereto. The internal stuff(60) is prepared by inserting zirconium(40) and a ferromagnetic member(30) into pottery stuff(10) and mixing zirconium(40) with the ferromagnetic member(30). Aluminum and stainless steel are molded into a frame of the internal vessel. In order to prevent the internal stuff(60) from being separated, the protrusions(50) are penetrated into the internal stuff(60).
