Abstract
A coil element according to one embodiment includes: an insulator body including first insulating layers and second insulating layers laminated in a stacking direction; first conductive patterns formed on the first insulating layers; second conductive patterns formed on the second insulating layers; a first to fourth external electrodes each provided on a bottom surface of the insulator body; and a first to fourth lead via conductive member. The insulator body includes a first portion and a second portion. The electrical resistivity of the first portion is higher than that of the second portion. The first portion covers upper and lower surfaces of at least one of intermediate first conductive patterns in the intermediate region. The first lead via conductive member, the second lead via conductive member, the third lead via conductive member, and the first lead via conductive member are arranged outside the first portion.
