A multilayer inductor is provided with a coil part including a coiled conductor and lead conductors, an outer sheath part covering the coil part and having an electrical isolation, and external electrodes electrically connected to the respective lead conductors. The lead conductors are located at both ends of the coiled conductor and have a width identical with that of the coiled conductor. The outer sheath part has two first side faces parallel to the axial direction of the coiled conductor and not adjacent to each other, and a second side face intersecting with the axial direction of the coiled conductor. Each external electrode has a first electrode portion formed throughout a direction perpendicular to the axial direction of the coiled conductor on the first side face. Each external electrode is not substantially formed on the second side face.

Coil component

A method of producing a multilayer electronic part having the shape of a substantially rectangular parallelopiped is constituted which has a multilayer body formed by superposing coil conductors and green sheets of a magnetic or nonmagnetic material. Terminal electrodes are formed respectively on both ends of the multilayer body along the direction of the magnetic flux generated when current is caused to flow through the coil conductors in the multilayer body. The terminal electrodes each has a conductive substrate formed within the area of the end of the multilayer body and including a lamination body as a component of the multilayer body.
