Abstract

PURPOSE:To permit a laminated transformer to be stronger and more compact as well as mass-production by alternately laminating an insulator layer of a magnetic ferrite or the like and a pair of conductor patterns for coil. CONSTITUTION:On the surface of an insulator layer 1, a pair of hook-shaped conductor patterns 2 and 3 for coil are printed, whose ends 4 and 5 extend to the lower side of the insulator layer 1 and whose inner ends 6 and 7 terminate at positions adjacent to each other. Then, rectangular insulator layers 8 and 9 are printed on the conductor patterns and the insulator of the lower layer. On doing this, the ends 6 and 7 of the conductor patterns on the lower layer are exposed to form the connections of the conductor patterns. Then, U-shaped conductor patterns 10 and 11 for coil whose inner-side portions are arranged adjacently to each other are printed. In addition, the inner ends of the patterns 10 and 11 form connections overlapped on the connections 6 and 7 of the lower conductor patterns, and the outer ends 12 and 13 extend to the upper side of the laminated body.
