Abstract
The present invention provides an inductor having high DC bias characteristics using a Fe alloy core and provides a method for manufacturing the same. The present invention relates to a wire-wound inductor which includes: a wire-wound inductor core obtained by grinding a compression molded mixed magnetic material powder including magnetic substance powder mixed with binder; and a metal conductive wire wound around a groove section of the wire-wound inductor core. For example, the magnetic substance powder has content ratio of 4 to 13 wt % of Si; 4 to 7 wt % of Al; the balance Fe; and unavoidable impurity. The magnetic substance powder has particle diameter distribution in which equal to or greater than 90% of the magnetic substance powder has particle diameter equal to or lower than 75 μm.
