1. A multilayer coil component comprising:
a multilayer body that includes insulating layers laminated in a length direction and that contain a coil; and
a first outer electrode and a second outer electrode that are electrically connected to the coil,
wherein the coil includes coil conductors that are laminated in the length direction together with the insulating layers and that are electrically connected to each other,
wherein the multilayer body has a first end surface and a second end surface that face each other in the length direction, a first main surface and a second main surface that face each other in a height direction perpendicular to the length direction, and a first side surface and a second side surface that face each other in a width direction perpendicular to the length direction and the height direction,
wherein the first outer electrode covers the entire first end surface,
wherein the second outer electrode covers the entire second end surface,
wherein a lamination direction of the multilayer body and an axial direction of the coil are parallel to the first main surface,
wherein a distance between the coil conductors adjacent to each other in the lamination direction is from 4 μm to 8 μm,
wherein each coil conductor includes a line portion and a land portion that is disposed at an end portion of the line portion,
wherein the land portions of the coil conductors adjacent to each other in the lamination direction are connected to each other with a via conductor interposed therebetween,
wherein a width of the line portion is from 30 μm to 50 μm,
wherein the first outer electrode extends from the first end surface, and covers a part of the first main surface, a part of the second main surface, a part of the first side surface, and a part of the second side surface, and
wherein when viewed in a direction orthogonal to the axial direction of the coil, the first outer electrode overlaps a portion of the coil conductor.
