    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 has a thickness of 4 to 19 μm, and 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 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.

    Abstract: One object is to compensate the reduction of the Q value due to reduction of core sectional area of a coil of an inductor, and the reduction of positional accuracy and adhesive strength of components mounted on a printed circuit board due to reduction of area of external electrodes, both caused by downsizing of component sizes. An inductor is provided which includes: a coil formed in an insulator and having one end and the other end thereof formed in a direction away from a mounting surface; and lead-out portions connected to the coil at positions more distant from the mounting surface than a portion of the coil closest to the mounting surface.
