    摘要： An element forming an electronic component has a first face and a second face facing each other, and a third face adjacent to each of the first face and the second face. A method of forming an external electrode of the electronic component involves a pre-formation step, first to third formation steps, and an electrode formation step. The pre-formation step is to apply a conductive paste onto the third face and to evaporate at least a part of a liquid contained in the applied conductive paste, to form a precoat portion expected to become a part of a third electrode portion. The first formation step is to apply the conductive paste from a direction opposite to the first face, onto the first face to form a first electrode portion. The second formation step is to apply the conductive paste from a direction opposite to the second face, onto the second face to form a second electrode portion. The third formation step is to apply the conductive paste onto the third face so as to cover the precoat portion, to form the third electrode portion. The electrode formation step is to dry the element to form the external electrode consisting of the first electrode portion, the second electrode portion, and the third electrode portion. The first electrode portion, the second electrode portion, and the third electrode portion are formed so as to connect with each other.

    摘要： 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.
