Abstract
A multilayer coil array includes an element body including a magnetic layer; first and second built-in coils; and first to fourth outer electrodes connected to the first and second coils. A non-magnetic layer is provided between the first and second coils. The first and second coils are each formed by a plurality of coil conductors being connected to each other. At least one out of a coil conductor of the first coil that is closest to the second coil among the plurality of coil conductors of the first coil and a coil conductor of the second coil that is closest to the first coil among the plurality of coil conductors of the second coil contacts the non-magnetic layer. The length of a coil conductor layer that contacts the non-magnetic layer of the coil conductor contacting the non-magnetic layer is different from the length of the other coil conductor layers.
