Abstract: In a multilayer body including a plurality of laminated insulating material layers on which a plurality of coil patterns are provided, the plurality of coil patterns are connected to each other to form a coil having a coil axis parallel to a lamination direction. A pair of outer electrodes connected to the coil are disposed at both ends in the lamination direction. When a direction orthogonal to the lamination direction is defined in an up-down direction, the coil patterns are disposed within the multilayer body so as to be shifted to an upper side. At least a portion of a vertical projection image of the coil on a virtual plane orthogonal to the lamination direction does not overlap a vertical projection image of the outer electrodes on the virtual plane.

Abstract: A laminated coil component has an element body formed by laminating a plurality of ceramic layers, and a coil conductor disposed inside the element body. The coil conductor has coil pattern portions disposed on the plurality of the ceramic layers and including line portions and land portions disposed at ends of the line portions, and pattern connecting portions connecting the land portion to each other between the coil pattern portions arranged adjacently in a laminating direction of the ceramic layers. The land portions overlap with the line portions located on the opposite side of the pattern connecting portions in the laminating direction when viewed in the laminating direction such that the centers of the land portions do not overlap with the line portions located on the opposite side of the pattern connecting portions in the laminating direction when viewed in the laminating direction.

Abstract: An electronic component that can be prevented from being shifted from a normal mount position and can be manufactured with a low cost is provided. The component is configured by stacking a plurality of insulating layers and a plurality of inner conductors provided on the respective insulating layers. The connection conductors have respective exposure portions that are each exposed between corresponding ones of the insulating layers at a surface of the stack. An outer electrode is formed, for example, by plating on the lower surface so that the exposure portions are covered with the outer electrode. The plurality of exposure portions do not have uniform thicknesses or are not arranged at uniform intervals in the stacking direction.
