Abstract
A coil includes a plurality of internal conductors that are electrically connected to each other and are disposed in an element body having magnetism. The plurality of internal conductors includes conductor portions that are separated from each other in a first direction and overlap each other when viewed from the first direction. At least one low-permeability layer is disposed along the conductor portions between the internal conductors adjacent to each other in the first direction. Permeability of the low-permeability layer is lower than permeability of the element body. The low-permeability layer includes a first portion contacting the internal conductors and at least one second portion separated from the internal conductors in the first direction, between the internal conductors adjacent to each other. The element body includes first element body regions that are interposed between the second portion and the internal conductors.
