Abstract:
A method for manufacturing laminated ferrite chip inductor arrays, comprising:forming ferrite sheets containing ferrite material; forming a plurality of through-holes at predetermined positions of the ferrite sheets; printing a plurality of coil shaped internal conductors with a conductor material in the ferrite sheets formed with the through-holes to form a plurality of first ferrite sheets with internal conductors; printing a plurality of conductor patterns of terminal electrodes with the conductor material in the ferrite sheets formed with the through-holes to form a plurality of second ferrite sheets with terminal electrodes; filling the conductor materials in the through-holes; laminating the plurality of first ferrite sheets with internal conductors between the plurality of second ferrite sheets with terminal electrodes in such a manner that a laminated face of each ferrite sheet is vertical with respect to an element mounting surface to be mounted to a circuit board; and obtaining a laminated body formed with the plurality of coil shaped internal conductors, the coiling direction of said coil shaped internal conductors being parallel with the element mounting surface, wherein the plurality of second ferrite sheets with the terminal electrodes are on an outer surface of the laminated body.
