PROBLEM TO BE SOLVED: To provide a laminated ferrite chip inductor array with improved structure for preventing defects of short circuits caused by migration in an inner conductive material, even if the body has a minute 2010 shape (length 2.0 mm, breadth 1.0 mm, and height 1.0 mm). SOLUTION: In a coil-shaped structural laminate, a plurality of ferrite sheets with a U-shaped inner conductive pattern are so laminated in layers that U-shaped inner conductive patterns on the adjoining sheets face opposite each other, and at the same time, the inner conductive printed patterns are connected electrically via a through-hole drilled in the ferrite sheet. An array includes a plurality of channels formed by annealing the coil-shaped structural laminated bodies and stored in a ferrite ceramic. In this case, each adjoining chip inductor are located with its inner conductive pattern shape at a rotated angle of 180 deg. with respect to each other. |
