1. A multilayer coil component comprising:
an element body formed by stacking a plurality of insulator layers and having a pair of end surfaces facing each other, a pair of main surfaces facing each other, and a pair of side surfaces facing each other, one of the main surfaces being a mounting surface;
a coil disposed in the element body and having a coil axis extending in a facing direction of the pair of main surfaces;
a first terminal electrode and a second terminal electrode connected to the coil and disposed on the mounting surface;
a first connection conductor disposed outside the coil in the element body when viewed in the facing direction, extending in the facing direction, and connecting one end of the coil located on a side of the other of the main surfaces and the first terminal electrode to each other; and
a second connection conductor connecting the other end of the coil located on a side of the one of the main surfaces and the second terminal electrode,
wherein the coil comprises a first coil portion and a second coil portion, each of the first coil portion and the second coil portion being formed on two or more of the plurality of the insulator layers, the first coil portion having the one end of the coil and being disposed on a side of the other of the main surfaces, the second coil portion having the other end of the coil and being disposed on a side of the one of the main surfaces, and
wherein a shortest distance between the first connection conductor and the second coil portion is larger than a shortest distance between the first connection conductor and the first coil portion.
