Abstract:
A laminated substrate embedded type inductor includes a laminated resin substrate in which a pair of first resin substrates are laminated, a sheet-shaped magnetic core placed in the laminated resin substrate, via holes provided so as to pass through the laminated resin substrate, and a coil formed via the via holes. The laminated resin substrate contains an adhesive component, wherein the sheet-shaped magnetic core is a molded body obtained by forming a soft magnetic flat metal powder into a flat plate, the soft magnetic flat metal powder is oriented in a plane of the flat plate, and a generated magnetic flux of the coil circulates in the plane of the flat plate, and wherein the magnetic core is integrated with the laminated resin substrate so that the adhesive component is impregnated in pores of the magnetic core.
