Abstract: A multilayer coil component includes an element body, first and second coils, and a pair of external electrodes. The element body includes a plurality of insulator layers laminated in a first direction. The element body has a pair of end surfaces opposing each other in a second direction orthogonal to the first direction. The first coil and the second coil are disposed in the element body and respectively have coil shafts along the second direction. The pair of external electrodes are disposed on the pair of end surfaces and electrically connected to both ends of the first coil and the second coil. The first coil includes a first conductor layer, a second conductor layer, and a first through hole conductor. The coil shaft of the first coil is disposed inside the second coil.
