On a food heating process, the Joule heating system has been received keen attentions as a sophisticated heating system because of accurate heating, non-scorching and cleanness. In a previous paper, we developed the visualizing method to observe and record the internal temperature profile as a picture in a food material and compared the visualized results with the data which simulated by a numerical analysis. However, a combined material exists in the container generally. In this paper, the measurement of potential distribution and numerical analysis are proposed and heat generation for the combined material is clarified.
