    Abstract: In an insulation layer of a coil component, a thickness of a second covering part and a third covering part located on the penetration hole side of a first covering part is thinner than that of the first covering part. A stray capacitance occurring between a flat coil pattern and external terminal electrodes is reduced by making the first covering part of the insulation layer thicker than the second covering part and the third covering part. Further, since the second covering part and the third covering part of the insulation layers are thinner than the first covering part, a magnetic volume is increased while external dimensions of the base body is maintained, and thus a high inductance is realized.

    Abstract: A coil component in which a change in thicknesses of the winding part is prevented is provided. According to the coil component, since each of a pair of neighboring resin walls and a seed part between the pair of resin walls are separated by a predetermined distance, a plating part grown on the seed part is easy to grow uniformly between the pair of neighboring resin walls. For this reason, the winding part whose surface is gentle and in which a change in thickness is prevented is obtained by plating growth.

    Abstract: In a coil component (planar coil element), at least part of a third metal magnetic powder constituting a metal magnetic powder and having a minimum average grain diameter is uncoated, which suppresses a reduction in magnetic permeability. On the other hand, the remaining metal powders are coated with glass, which improves the insulating properties of a metal magnetic powder-containing resin and reduces core loss.

    Abstract: A coil component includes a substrate, a planar spiral conductor formed on a top surface of the substrate, a lead conductor connected to an outer peripheral end of the planar spiral conductor, a dummy lead conductor formed on the top surface of the substrate between an outermost turn of the planar spiral conductor and an end of the substrate and free from an electrical connection with another conductor within the same plane, external electrodes and arranged in parallel with the top surface of the substrate, and a bump electrode formed on a surface of the lead conductor and connects the lead conductor with the external electrode. The external terminals have a larger area than the bump electrodes for securing a bonding strength.

    Abstract: In a planar coil element and a method for producing the same, a metal magnetic powder-containing resin containing an oblate or needle-like first metal magnetic powder contains a second metal magnetic powder having an average particle size (1 μm) smaller than that (32 μm) of the first metal magnetic powder, which significantly reduces the viscosity of the metal magnetic powder-containing resin. Therefore, the metal magnetic powder-containing resin is easy to handle when applied to enclose a coil unit, which makes it easy to produce the planar coil element.
