Abstract:
A multi-layered chip inductor comprising:a coil-shaped internal conductor inside a ceramic laminate, said coil-shaped internal conductor being spiralled around an axial line in a laminating direction of said ceramic laminate, wherein said coil-shaped internal conductor is formed by a plurality of internal conductor patterns laminated on a plurality of ceramic laminate pieces, the ceramic laminate pieces and the internal conductor patterns being laminated on top of one another in the laminating direction to form a ceramic laminate having two laminating direction surfaces, the plurality of internal conductor patterns being connected through via holes in the ceramic laminate pieces; and external electrodes disposed on an entirety of both laminating-direction surfaces of said ceramic laminate, said external electrodes being electrically connected to respective ends of said coil-shaped internal conductor, wherein peripheral shapes of the external electrodes are identical to peripheral shapes of said laminating-direction surfaces.
