Abstract
A multi-layered inductor array is constructed to reduce and minimize variations in the inductance values and DC resistance values of a plurality of inductors contained in a multi-layered structure. In this multi-layered inductor array, four spiral inductors having an equal number of winding turns are aligned from the left end surface of the multi-layered structure to the right end surface thereof. In the direction in which the four spiral inductors are aligned, the lengths of the spiral portions of the inductors positioned at the central portion of the multi-layered structure are greater than those of the spiral portions of the spiral inductors positioned at both end portions thereof.
