Abstract: A laminated coil component includes: an element body having a first surface and a second surface facing each other in a first direction; a coil unit formed by laminating a plurality of coil conductors in a second direction orthogonal to the first direction inside the element body; a first lead-out conductor; and a second lead-out conductor. A first coil conductor adjacent to the first lead-out conductor in the second direction includes a first side portion extending along the first surface, on a first surface side. A second coil conductor adjacent to the second lead-out conductor in the second direction includes a second side portion extending along the second surface, on a second surface side. The first side portion has a larger line width than other side portions of the first coil conductor and the second side portion.
