Abstract
A laminated coil component is configured by laminating a plurality of magnetic layers and a plurality of coil conductors in a lamination direction. In a cross-section taken along a width direction of the coil conductors, each coil conductor has a first surface on one side in the lamination direction, a second surface on another side in the lamination direction, and side surfaces on both sides in the width direction. The second surface makes contact with the magnetic layer. A hollow cavity portion is formed between the magnetic layer, and the first surface and both side surfaces. The hollow cavity portion has a first extended portion, extending outward in a direction intersecting with the lamination direction, on the first surface side, on at least one of both end sides in the width direction.
