    摘要： An inductive component for a DC/DC converter is made by transferring a copper track (2) from a copper substrate (1) to a first ferrite plate (3). A second ferrite plate (5) is attached by glue to the first ferrite plate so that the track (2) forms an inductor coil sandwiched between the two ferrite plates (3,5). One of the plates has holes (4) in registration with the terminals of the coil, and these holes are filled with solder (5) to provide externally accessible contacts.

    摘要： DC bias characteristics of an open magnetic circuit type layered coil component are improved.
    A layered coil component (1) includes a coil that is constructed by layering coil conductor patterns (5) and ceramic sheets. The ceramic sheets include a first ceramic sheet and a third ceramic sheet (4) having a permeability lower than the permeability of the first ceramic sheet. The third ceramic sheet (4) has an arrangement that is astride at least two of the coil conductor patterns (5) adjacent to each other in a layering direction, in a section including a coil axis of the coil (L).

    摘要： A high frequency coil having a structure in which strip-like coil conductors are formed on the surfaces of an insulating substrate, and a method of manufacturing the coil. An object of the invention is to increase the Q value of the coil without increasing the film thickness and wire width of the coil conductors. A pair of coil conductors (3, 4) are so formed that the coil conductors sandwich an insulating substrate (1). The paired coil conductors (3, 4) are so connected in parallel to each other that currents flow through them in the same direction. The ends of the paired coil conductors (3, 4) are connected electrically with an input and an output electrode (5, 6) formed on the insulating substrate (1).
