Abstract: A coil component includes an element body, a coil provided in the element body, and an outer electrode provided in the element body and electrically connected to the coil. The outer electrode is embedded in one surface of the element body such that a protruding portion, which is a portion of the outer electrode, protrudes from the one surface of the element body. Also, a thickness of an embedded portion, which is a portion of the outer electrode and is embedded in the one surface of the element body, is larger than a thickness of the protruding portion of the outer electrode protruding from the one surface of the element body in thickness in a direction perpendicular to the one surface of the element body.

Abstract: A coil component including an element assembly that includes a support substrate having a cavity, a first coil disposed on a first principal surface of the support substrate, a second coil disposed on a second principal surface of the support substrate, and a magnetic portion. The coil component further includes first and second outer electrodes electrode electrically coupled to the first coil, and third and further outer electrodes electrically coupled to the second coil. Each outer electrode is disposed on the surface of the element assembly. The cavity of the support substrate, the core portion of the first coil, and the core portion of the second coil overlap at least one another when viewed in the direction perpendicular to the principal surface. The magnetic portion is disposed in at least the cavity and the two core portions. Also, the support substrate is formed of sintered ferrite.

Abstract: A coil component includes an element body including a magnetic portion containing metal particles and a coil conductor embedded in the magnetic portion, and at least a pair of outer electrodes disposed on the element body and electrically connected to the coil conductor. The magnetic portion includes a region A containing metal particles having a relatively small average particle size and a region B containing metal particles having a relatively large average particle size. The region A is present between outer electrodes of the pair of outer electrodes and the coil conductor.
