Abstract: A coil component comprising a coil conductor layer wound on a plane, an outer-circumferential lead-out conductor led out on the same plane as the coil conductor layer from an outer-circumferential end of the coil conductor layer, and an inner-circumferential lead-out conductor led out on the same plane as the coil conductor layer from an inner-circumferential end of the coil conductor layer. The coil component further comprises a branch conductor disposed to branch from at least one of the outer-circumferential lead-out conductor and the inner-circumferential lead-out conductor, and extending on the same plane as the coil conductor layer.

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.
