Abstract
To provide a stacked coupling coil component capable of achieving a desired coupling coefficient while suppressing the height of the component. A stacked coupling coil component 1 has conductor layers L1, L3, and L5 respectively including spiral coils 11 to 13, conductor layers L2, L4, and L6 respectively including spiral coils 21 to 23, and a conductor layer L7 including spiral coils 31 and 41 which are disposed at mutually different planar positions. The spiral coils 11 to 13 and 21 to 23 overlap one another. The spiral coils 11 to 13 and 31 are connected in series between terminal electrodes E1 and E2, the spiral coils 21 to 23 and 41 are connected in series between terminal electrodes E4 and E3. This allows adjustment of a coupling coefficient, making it possible to achieve a desired coupling coefficient while suppressing the height of the component.
