Abstract: A coil component includes an element body including a multilayer body in which a first ferrite layer, a first glass layer, and a second ferrite layer are laminated in that order; a coil embedded in the first glass layer; and an outer electrode provided on an outer surface of the element body and electrically connected to the coil. The first glass layer includes regions in which Cu and Mg coexist.

Abstract: A multilayer-type coil component including an element body including insulating layers laminated in a laminating direction; first and second coils inside the element body and insulated from each other; first and second outer electrodes on a surface of the element body and electrically connected to the first coil; third and fourth outer electrodes on the surface of the element body and electrically connected to the second coil. The laminating direction, and respective directions of coil axes of the first and second coils are parallel to a mount surface of the element body along a same direction. The first and second coils include first and second coil conductors, respectively, laminated in the laminating direction. Each of the first coil conductors has a length smaller than one turn of the first coil. Each of the second coil conductors has a length smaller than one turn of the second coil.
