  • Patent number: 12224104
    Abstract: An electronic component includes: an element body in which a plurality of insulator layers are stacked; a coil in which a plurality of inner conductors installed in the element body are electrically connected to each other; and an outer electrode that is disposed on an outer surface of the element body, is electrically connected to the coil, and includes at least a baked electrode layer. The inner conductor connected to the outer electrode includes a connection conductor that electrically connects the baked electrode layer to the inner conductor. The connection conductor includes a protruding portion that protrudes from the outer surface of the element body to the outer electrode. The protruding portion includes a metal having a smaller diffusion coefficient than a metal of a main component included in the baked electrode layer. The inner conductors have a lower electric resistance value than the metal included in the protruding portion.
