1. A coil device, comprising:
a first core;
a second core combined with the first core and having a main surface configured to face a mounting substrate and a side surface perpendicular to the main surface;
a first conductor and a second conductor arranged adjacent to each other between the first core and the second core; and
a magnetic body provided integrally or separately with the first core or the second core, wherein
at least one of the first core and the second core includes (i) a center leg portion located between the first conductor and the second conductor and constituting the magnetic body and (ii) a pair of outer leg portions arranged on both sides of the center leg portion,
the first conductor has (i) a first main body portion arranged between the first core and the second core and (ii) a first mounting portion continuous to the first main body portion and arranged over the side surface,
the second conductor has (i) a second main body portion arranged between the first core and the second core and (ii) a second mounting portion continuous to the second main body portion and arranged over the side surface,
the first mounting portion has a first lateral protruding portion protruding on one side in a first direction (Y-axis direction) from the first main body portion and the second mounting portion has a second lateral protruding portion protruding on the other side in the first direction (Y-axis direction) from the second main body portion, and
the first mounting portion and the second mounting portion extend parallel to the side surface as a whole and lower ends of the first lateral protruding portion and the second lateral protruding portion protrude downward from the main surface in a direction from the first core to the second core along the side surface without bending.
