Abstract
A planar magnetic deviceincluding a first magnetic layer, a second magnetic layer, and a planar coildisposed between the first magnetic layerand the second magnetic layer, wherein magnetic particleshaving a shape ratio S/L of 0.7 to 1 when a length of a long axis is L and a length of a short axis orthogonal to the long axis is L are filled in a gap W between coil wirings of the planar coil. According to the planar magnetic device, it is possible to realize a planar magnetic device such as an inductor reduced in height by using fine particles that enable to effectively obtain a large inductance value.
