<p>PURPOSE:To reduce loss in an inductance part by preparing gaps between the central magnetic leg of an E-shaped core, outer magnetic legs of the core, and bar type cores placed between the three magnetic legs so made as to have a structure which hardly generates eddy current. CONSTITUTION:Since between the central magnetic leg 5, outer magnetic legs 6, and bar type cores 2 gaps 4 are made, the gap size does not cause the height of an inductance part to change. Further, fluxes 7 that are generated in gaps 4 traverse the flat part of a conductive member 8 formed into a printed coil 3 at an angle close to the parallel direction, and further since multistage gaps are prepared, the structure of the inductance part is so made that it hardly generates eddy current and provides the effect of reducing the loss in the inductance part.</p> |
