1. A multilayer coil component comprising:
an element body formed by stacking a magnetic body layer containing a plurality of metal magnetic particles of a soft magnetic material;
a first coil disposed in the element body and configured to include a plurality of first coil conductors;
a second coil disposed in the element body and configured to include a plurality of second coil conductors;
a first external electrode to which one end portion of each of the first coil and the second coil is connected; and
a second external electrode to which the other end portion of each of the first coil and the second coil is connected, wherein
the first coil and the second coil are separated from each other in a stacking direction of the magnetic body layer in the element body, and
between the first coil and the second coil of the element body, at least a region where the first coil and the second coil overlap when viewed from the stacking direction is higher in electrical resistivity than the magnetic body layer.
