Abstract
A combined-type coil device provided with a core, a first coil and a second coil, where the core is provided with at least four through holes and the through holes are roughly parallel to one another. When a combination of two through holes constitutes a first through holes pair and the combination of the remaining two through holes constitutes a second through holes pair, a center line passing through the centers of the holes in the first through hole pair and a center line passing through the centers of the holes in the second through hole pair extend almost perpendicular to each other. The first coil passes through the first through hole pair, whereas the second coil passes through the second through hole pair.
