Abstract: An inductor array chip includes a magnetic laminated body and a plurality of inductors. The magnetic laminated body includes a plurality of stacked magnetic layers. The plurality of inductors are arranged inside the magnetic laminated body. The inductance of a first inductor differs from the inductance of a second inductor. The inductors include a plurality of coil-shaped conductors and via-hole conductors. The plurality of coil-shaped conductors are arranged between the magnetic layers. The via-hole conductors electrically connect the plurality of coil-shaped conductors. The inductors include a plurality of inductors in which the section sizes of the coil-shaped conductors differ from one another.
