抄録

The objects of this study are improvement and estimation of thin plate quality (thickness D_s is about 0.1 ≦ D_s ≦ 1.0[mm]) that has electric insulating property and more greater thermal conductivity than proper plastics. In this report we have been tried numerical calculation about temperature field having thin and narrow film heater. The two dimensional temperature field is used for consideration as first approximation. The solution of simultaneous heat conduction equations under initial and boundary conditions is obtained by numerical simulation based on finite difference method. The author have been obtained calibration curves between temperature rising ratio and thermal conductivity of various materials.
