Abstract

One object is to provide a laminated inductor having a reduced thickness without reduction in the magnetic characteristic and the insulation quality. The laminated inductor includes a first magnetic layer, an internal conductor, second magnetic layers, third magnetic layers, and a pair of external electrodes. The first magnetic layer includes three or more magnetic alloy particles arranged in the thickness direction and an oxide film binding the magnetic alloy particles together and containing Cr. The three or more magnetic alloy particles have an average particle diameter of 4 μm or smaller. The internal conductor includes a plurality of conductive patterned portions electrically connected to each other via the first magnetic layer. The second magnetic layers are composed of magnetic alloy particles and disposed around the conductive patterned portions. The third magnetic layers are composed of magnetic alloy particles and disposed so as to be opposed to each other in thickness direction.
