PROBLEM TO BE SOLVED: To constitute a laminated chip inductor by which DC overlapping characteristics are improved without a limitation by the length of a magnetic-substance laminate and in which optimum characteristics can be obtained. SOLUTION: A plurality of through-holes 3 are disposed to the magnetic-substance laminate 1, and a plurality of conductor paths 30 are formed by a filling with a conductor. A coil is formed by forming wiring patterns 2a and 2b connected to each conductor path 30 at specified places respectively on the top face and underside of the magnetic-substance laminate 1. The coil is formed by arranging four unidirectional wound-coil constituting sections 11 to 14 in parallel and connecting the constituting sections 11 to 14 in series, and a meandering flux path is formed by making a current flow through the coil. The flux path of an arbitrary length can be formed without the limitation by the length of the magnetic-substance laminate 1 by such a constitution. COPYRIGHT: (C)2004,JPO&NCIPI
