  • Publication number: 20230420182
    Abstract: A coil-component manufacturing method includes producing an unfired multilayer body block including a stack of an unsintered magnetic layer and an unsintered coil conductor layer; applying pressure to the unfired multilayer body block; and by firing the unfired multilayer body block, producing a fired multilayer body block including a stack of a magnetic layer and a coil conductor layer. The method also includes impregnating the fired multilayer body block with resin; by scribing a surface of the fired multilayer body block impregnated with the resin, forming a break start point in the surface of the fired multilayer body block; by breaking the fired multilayer body block impregnated with the resin into individual chip units, producing a multilayer body; and by plating, forming an outer electrode on an outer surface of the multilayer body or on an outer surface of the fired multilayer body block.

  • Patent number: 10249429
    Abstract: At the position where the lead art of the wire is projecting out from the outer face of the core part and spaced apart from the side face, the bonding part between the lead part and the terminal electrode is formed. The terminal electrode comprises the terminal body installed along the side face of the core body, and the lead supporting part bended from the terminal body towards the bonding part at the near position where the lead part projects out from the side face of the core part. The crossing angle of the lead supporting part with respect to the side face of the core body is less than 90 degrees.
