Document Type and Number:
Japanese Patent JP7159938
Kind Code:
B2
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.
