Abstract:
1. A filter circuit comprising: a multilayer body including a plurality of dielectric layers stacked on top of one another in a stacking direction; a first inductor including first conductive patterns provided on the plurality of dielectric layers and arranged so as to be superposed with one another in the stacking direction; a second inductor including second conductive patterns provided on the plurality of dielectric layers and arranged so as to be superposed with one another in the stacking direction; and a third inductor including third conductive patterns provided on the plurality of dielectric layers and arranged so as to be superposed with one another in the stacking direction; wherein the first inductor is connected in series with the second inductor; a first end of the third inductor is connected to a connection point between the first inductor and the second inductor, and a second end of the third inductor is directly connected to a ground potential; the first conductive patterns, the second conductive patterns and the third conductive patterns are respectively provided on the same plurality of dielectric layers.
