Abstract
A multilayer inductor for reducing a difference in inductance values and suppressing magnetic interference. Plural electrically insulating magnetic layers and conductive patterns are laminated, each of the conductive patterns being connected in sequence in the lamination direction, so that two coils having substantially the same number of turns and substantially the same coil diameter are formed, the two coils are in parallel such that each coil is a mirror image with respect to a virtual surface between the coils, and ends of each coil are located at an outer peripheral part on a side opposite to the virtual surface, an electrically insulating nonmagnetic pattern corresponding in shape to each of the conductive patterns is between the conductive patterns adjacent in the lamination direction, and at least one electrically insulating nonmagnetic layer is disposed only inside the coils in the lamination direction in place of the magnetic layers.
