Laminated coil component and matching circuit

A laminated coil component comprising:

• a conductor pattern including a first coil conductor pattern and a second coil conductor pattern;
• a plurality of insulating layers including at least one insulating layer on which the conductor pattern is provided, the plurality of insulating layers laminated on each other;
• and
• at least one coil defined by the conductor pattern;
• wherein
• the first coil conductor pattern defines a coil opening that generates a magnetic flux in a first direction;
• the second coil conductor pattern defines a first coil opening that generates a magnetic flux in the first direction and a second coil opening that generates a magnetic flux in a second direction opposite to the first direction when an electric current flows from one end of the second coil conductor pattern towards another end of the second coil conductor pattern;
• the coil opening of the first coil conductor pattern, in a plan view, overlaps a plurality of coil openings including the first coil opening and the second coil opening of the second coil conductor pattern;
• the first coil conductor pattern has a loop shape or a substantial loop shape;
• the second coil conductor pattern includes an 8-shaped structure or a substantially 8-shaped structure on a single insulating layer of the plurality of insulating layers;
• and
• in a plan view, a total area of the first coil opening in which the coil opening of the first coil conductor pattern overlaps the first coil opening is different from a total area of the second coil opening in which the coil opening of the first coil conductor pattern overlaps the second coil opening.
