  • Publication number: 20230230742
    Abstract: A multilayer coil component includes an element body including an end surface, a coil disposed in the element body, and an external electrode disposed on an end portion of the element body and connected to the coil. The external electrode includes a conductive resin layer. The conductive resin layer includes resin and a plurality of metal particles and is in contact with the end surface. The conductive resin layer includes a metal particle group. The metal particle group consists a plurality of first metal particles included in the plurality of metal particles, and the plurality of first metal particles is adjacent to the end surface and separated from the end surface.

  • Publication number: 20230230738
    Abstract: A coil component includes an element body, a coil and a first electrode part. The element body includes a main surface which is used as a mounting surface. The coil is disposed in the element body. The first electrode part is embedded in the element body and electrically connected to the coil. The first electrode part includes a first surface exposed from the main surface and a second surface opposing the first surface. An area of the first surface is larger than an area of the second surface when viewed from a direction orthogonal to the first surface.

  • Publication number: 20230223183
    Abstract: The coil component includes an element body, a coil, a first electrode part and a second electrode part. The element body includes a main surface to be used as a mounting surface. The coil is disposed in the element body. The first electrode part and the second electrode part are spaced apart from each other in a first direction, embedded in the element body in such a way as to be exposed from the main surface, and electrically connected to the coil. The first electrode part includes a first surface exposed from the main surface and a protrusion disposed in the element body in such a way as to be spaced apart from the main surface. The protrusion protrudes more toward the second electrode part than the first surface in the first direction.
