Abstract
This disclosure provides a laminated inductor capable of suppressing concentration of magnetic gap portions, preventing local magnetic saturation, and obtaining excellent DC superposition characteristics. In an embodiment of a laminated inductor, magnetic layers and coil conductors are alternately laminated. The laminated inductor includes plural first mixed layers and plural second mixed layers. Each first mixed layer includes a first nonmagnetic material portion between ones of the conductive patterns overlapping in a lamination direction and a second nonmagnetic material portion that is inside the coil conductor and connected to the first nonmagnetic material portion. Each second mixed layer includes a nonmagnetic material portion between ones of the conductive patterns overlapping in the lamination direction and a nonmagnetic material portion that is outside the coil conductor and is connected to the first nonmagnetic material portion. The plural first mixed layers and the plural second mixed layers are formed as different layers.
