1. 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 toward 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 the 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
an outline of the first coil conductor pattern overlaps an outline of the second coil conductor pattern such that the outline of the first coil conductor pattern is the same or substantially the same as the outline of the second coil conductor pattern when viewed in a plan view.
