  • Publication number: 20230298799
    Abstract: A coil component includes a winding part and a magnetic base body. The winding part is constituted by a wound conductor. The magnetic base body includes a first magnetic portion and a second magnetic portion. The first magnetic portion has first metallic particles bonded together. An average particle diameter of the first metallic particles is a first particle diameter. The second magnetic portion has second metallic particles bonded together. An average particle diameter of the second metallic particles is a second particle diameter. The magnetic base body encapsulates the winding part. The second particle diameter is larger than the first particle diameter. At least a portion of the first magnetic portion is present around the winding part.

  • Patent number: 10475569
    Abstract: One object is to compensate the reduction of the Q value due to reduction of core sectional area of a coil of an inductor, and the reduction of positional accuracy and adhesive strength of components mounted on a printed circuit board due to reduction of area of external electrodes, both caused by downsizing of component sizes. An inductor is provided which includes: a coil formed in an insulator and having one end and the other end thereof formed in a direction away from a mounting surface; and lead-out portions connected to the coil at positions more distant from the mounting surface than a portion of the coil closest to the mounting surface.
