Abstract: A multilayer inductor has a rectangular parallelepiped element body and its length in the lengthwise direction (L), length in the direction of height (H), and length in the direction of width (W) are L≦0.6 mm, H≦0.3 mm, and W≦0.3 mm, respectively. Terminal electrodes are provided so as to cover the vertices of the element body and come round to the side face from the end faces on both sides. The radius of curvature R of the vertex of the terminal electrode is set to a value being 10% or more and 20% or less of H or W.

Abstract: 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.
