<p>PURPOSE:To enhance the transmission efficiency while reducing noise by a structure wherein the conductor wirings for coupling a transformer are filled tightly in winding slots in flush with the opposing faces of cores while being connected, at the end parts with connection lands formed on the surface on the opposite side. CONSTITUTION:A thin copper film 36 is cut to form insulating grooves 41, 42 around through holes 43, 44. Consequently, connection lands 39, 40 are formed in the insulating grooves 41, 42 formed circularly. Winding slots 64, 65 are filled tightly with windings 62, 63 of thin copper film having surfaces in flush with those of the cores 67, 68. Since reactive flux passing through the winding slots 64, 65 is not generated, the transmission efficiency is enhanced significantly.</p> |
