  • Patent number: 11875929
    Abstract: A coil component including a body having a magnetic portion including a metal magnetic particle and a resin, and a coil conductor embedded in the magnetic portion, and an outer electrode provided on a surface of the body and connected to the coil conductor. The coil conductor is a wound body of a conductive wire covered with an insulating film, and has a first surface and a second surface facing each other in a winding axis direction. Also, on the first surface of the coil conductor, a first resin portion is provided at least either on a surface of the conductive wire or in a gap between adjacent ends of the conductive wire.
    Type: Grant

  • Patent number: 11763985
    Abstract: A method of manufacturing a coil component includes arranging a plurality of coil conductors that is a wound body of a conductive wire, and each has opposing first and second surfaces, in a winding axis direction on a surface of an adhesive layer in contact with the first surface, manufacturing a processed body by placing a first magnetic sheet including a first metal magnetic particle and a first resin on a side of the second surface of each of the coil conductors and performing press processing on the first magnetic sheet, manufacturing an aggregate base body by peeling the processed body from the adhesive layer, placing a second magnetic sheet including a second metal magnetic particle and a second resin on a side of the first surface of each coil conductor, and press processing the second magnetic sheet, and manufacturing a body by individualizing the aggregate base body.
