Abstract

PURPOSE:To obtain the laminated coil of the open magnetic circuit type and contrive the wide range improvement of a superposition characteristic and a temperature characteristic by a method wherein a nonmagnetic insulator layer comprised of ceramics of ZnO-Bi2O3-CuO system is inserted between the laminations of magnetic bodies. CONSTITUTION:Magnetic ferrite powders knealed with a suitable binder to be made paste are printed in sheetlike to form a magnetic body layer 1, and a conductive paste of Pd-Ag and the line is printed setting aside the upper part of the layer 1 to form a conductor 2. A conductor pattern extending spirally between the magnetic body layers is formed in the same manner. Then, the nonmagnetic insulator layer 7 is printed using the paste containing the ceramic powders of the ZnO-Bi2O3- CuO system, and one end of the conductor 6 is exposed and the magnetic body layer 9 is printed again. Thus, magnetic fluxes are not leaked outside the laminated bodies due to the magnetic body layers 1, 11, a part corresponding to a gap being formed due to the presence of the insulator layer 7, the laminated coil of the open magnetic circuit type being obtained, and the temperature characteristic or the like can largely be improved.
