MULTILAYER INDUCTOR STRUCTURE

The present invention relates to a multilayer inductor structure including a plurality of magnetic layers and metal electrode tracks formed on the magnetic layers, in which a ceramic-inorganic material composite is provided in a magnetic core region of a coil pattern formed by the metal electrode tracks, the ceramic-inorganic material composite including two or more first layers and second layers, the first layer contains a ceramic material of which the curve slope of the dielectric constant with temperature change is positive, the second layer contains an inorganic material of which the curve slope of the dielectric constant with temperature change is negative, and the first layer and the second layer are stacked on each other in an alternating manner; in addition, due to the arrangement mode of the metal electrode tracks, the ineffective space, without magnetic lines, between every two adjacent metal electrode tracks is minimized. According to the multi-layer inductor, stable device characteristics can be a
