    Abstract: A multilayer inductor for reducing a difference in inductance values and suppressing magnetic interference. Plural electrically insulating magnetic layers and conductive patterns are laminated, each of the conductive patterns being connected in sequence in the lamination direction, so that two coils having substantially the same number of turns and substantially the same coil diameter are formed, the two coils are in parallel such that each coil is a mirror image with respect to a virtual surface between the coils, and ends of each coil are located at an outer peripheral part on a side opposite to the virtual surface, an electrically insulating nonmagnetic pattern corresponding in shape to each of the conductive patterns is between the conductive patterns adjacent in the lamination direction, and at least one electrically insulating nonmagnetic layer is disposed only inside the coils in the lamination direction in place of the magnetic layers.

    Abstract: There is provided a winding component capable of reducing the core temperature compared to the past even in a usage scenario where the amount of core heat generation is great, and whose size and weight may be reduced as a result. The present invention is a winding component including a coil (2) and a pair of upper and lower cores (4, 5) that form a closed magnetic path by surrounding an outer perimeter of the coil (2), the winding component having a bottom surface of the lower core (5) mounted on a housing (1) with a heat dissipation function, where a metal plate (7) having a higher thermal conductivity than the lower core (5) is attached to an outer side surface (6) of the lower core (5).

    Abstract: A coil device includes two core members, one of which is E-shaped. The E-shaped core member has left and right side faces, and a center leg that extends in a vertical direction. A conducting wire is wound around a core, the core being composed of the two core members arranged to face each other in the vertical direction with a gap between the two core members. The conducting wire is wound around the center leg. First and second heat-sinking plates made of metal are bent so as to be in contact with upper and side faces of the core. The first and second plates are arranged so that first edges of the plates are placed left-right symmetrically with respect to the core with a gap between the edges. Second edges of the plates are in contact with a metal heat-sinking board where the core is placed.

    Abstract: A multilayer inductor providing improved DC superposition characteristics by a permanent magnet that emits a bias magnetic flux, and having a low-loss material as a magnetic body to improve converter conversion efficiency. The multilayer inductor has a plurality of laminated electrically insulating magnetic layers; and laminated conductive patterns, each of the conductive patterns being connected in sequence in the lamination direction forming a spiral coil inside the magnetic layer. An magnetized annular permanent magnet layer emits a magnetic flux whose direction is opposite that of a magnetic flux excited by the coil is between an outer peripheral edge of the inductor and an outer peripheral edge of the coil so as not to overlap an inner peripheral part of the magnet layer with the conductive patterns and so as to block a space between the conductive patterns and the magnet layer, in axial view of the coil.
