    Abstract: A coil component has a first surface and a second surface facing each other. The coil component has a coil conductor formed into a spiral shape, an insulating resin layer covering the coil conductor, a magnetic resin layer disposed on the first surface side of the insulating resin layer without being disposed on the second surface side of the insulating resin layer, and an external terminal disposed at least on one surface on the first surface side of the magnetic resin layer and electrically connected to the coil conductor. The magnetic resin layer is made of a composite material of a resin and a metal magnetic powder. The external terminal includes a metal film contacting the resin and the metal magnetic powder of the magnetic resin layer.

    Abstract: An inductor component comprises an element body; first and second inductors in the body; first and second columnar wirings in the body with end surfaces exposed from a first principal surface of the body and electrically connected to the first inductor; third and fourth columnar wirings in the body with end surfaces exposed from the first principal surface and electrically connected to the second inductor; first through fourth external terminals contacting the end surfaces of the first through fourth columnar wirings, respectively; and an insulating film on the first principal surface covering a portion of the end surface of the first and third columnar wiring not contacting the first and third terminals, respectively. The first terminal is closer to the third terminal than the fourth terminal, and a shortest distance between the first and third terminals is longer than a shortest distance between the first and third columnar wirings.

    Abstract: An electronic component comprising an element body including opposite first and second end surfaces, and an upper surface connecting the first and second end surfaces; a circuit element embedded in the element body; a first lead-out electrode embedded on the first end surface side and electrically connected to the circuit element; a columnar electrode arranged separately from the first lead-out electrode in a first direction viewed in a direction orthogonal to the first end surface, and embedded in the element body with a portion exposed from the first end surface to the upper surface; and a first via conductor connecting the first lead-out and columnar electrodes. An exposure width of the first via conductor, on the first end surface along a second direction orthogonal to the first direction viewed in the direction orthogonal to the first end surface, is smaller than the exposure width of the columnar electrode.

    Abstract: An electronic component includes a main body made of an insulator, a circuit element positioned inside the main body, and outer electrodes. The outer electrodes are constituted of bottom surface electrodes and post-like electrodes. The post-like electrodes are extended from a bottom surface of the main body toward the interior of the main body. Further, the post-like electrodes are embedded in the main body, and parts of the post-like electrodes are exposed to side surfaces of the main body. Furthermore, the bottom surface electrodes are made of a resin containing metal powder.
