1. A winding-type coil component, comprising:
a core including a winding core portion and a first flange portion and a second flange portion, the first flange portion and the second flange portion being provided on a first end of the winding core portion and a second end of the winding core portion, respectively, the first end and the second end being opposite to each other; and
a first wire and a second wire wound around the winding core portion with substantially the same number of turns, not electrically connected to each other, and having a twisted wire portion where the first wire and the second wire are twisted together,
wherein the winding-type coil component is configured to be mounted on a mount board with the winding core portion oriented parallel to the mount board,
a sectional shape of the winding core portion that is perpendicular to a central axis thereof is a substantially protruding shape extending towards the mount board, and
when viewed from the mount board, a facing area of the nearest wire to the mount board between the first wire and the second wire is smaller than a facing area of the other wire between the first wire and the second wire, and the other wire between the first wire and the second wire extends from the nearest wire to a first edge of the core and extends from the nearest wire to a second edge of the core opposite from the first edge.
