Abstract:
A stacked coil element includes a stack including a plurality of insulating layers and a coil conductor structure with a winding axis in a thickness direction, and conductor patterns defining a portion of a coil provided on the insulating layers and electrically connected in the thickness direction. The stack includes a coil inner hole on an inner peripheral side of the coil conductor structure, the coil inner hole penetrating in the direction of the winding axis or having the direction of the winding axis as a depth direction. In at least one of the plurality of insulating layers, an end surface of the conductor pattern on the coil inner hole side is in the same plane as an end surface of the insulating layer on the coil inner hole side.
