Abstract:
An LC-included component comprising:at least two LC resonators, each of said at least two LC resonators including at least one inductor and at least one capacitor, said at least one inductor and said at least one capacitor provided in a laminated unit defined by stacked insulating layers, wherein: said at least one inductor of each of said at least two LC resonators is defined by via holes successively connected in a stacking direction in which the insulating layers are stacked; said at least one inductor of said at least two LC resonators being arranged in an X direction of an X-Y plane; a mutual inductance being produced between the at least one inductor of a first of said at least two LC resonators and the at least one inductor of a second of said at least two LC resonators, and said at least two LC resonators being magnetically coupled; and each of said via holes having a section shape on the X-Y plane that is substantially perpendicular to said stacking direction such that a dimension in the Y direction is greater than a dimension in the X direction.
