A multilayer coil component that includes a multilayer body formed by stacking a plurality of insulating layers on top of one another and that has a coil built into the inside thereof; and a first outer electrode and a second outer electrode that are electrically connected to the coil. The coil is formed by electrically connecting a plurality of coil conductors, which are stacked together with insulating layers, to one another. A first main surface of the multilayer body is a mounting surface. A stacking direction of the multilayer body and an axial direction of the coil are parallel to the mounting surface. At least one of the coil conductors is provided with an expanded region that has a line width that is larger than a coil line width in a plan view from the stacking direction.
