摘要： An electronic component includes an element body and an external electrode disposed on the element body. The external electrode includes a sintered metal layer and a conductive resin layer. The conductive resin layer is formed over the sintered metal layer and the element body. An average thickness of the conductive resin layer is smaller than that of the sintered metal layer.

摘要： An electronic component includes an element body of a rectangular parallelepiped shape, an external electrode, and an insulating film. The element body includes a first principal surface as a mounting surface, and a first side surface adjacent to the first principal surface. The external electrode includes a first electrode part and a second electrode part. The first electrode part is disposed on the first principal surface. The second electrode part is disposed on the first side surface and connected to the first electrode part. The insulating film continuously covers an end edge of the first electrode part and at least a part of an end edge of the second electrode part.

摘要： In a method for manufacturing a laminated coil component, in which a laminated coil component is manufactured by laminating insulator sheets in order on which conductors having predetermined patterns are formed, the insulator sheets are laminated such that a distance in a lamination direction between a first lead-out conductor laminated first and a first coil conductor laminated next is larger than a distance in the lamination direction between a second lead-out conductor laminated last and a second coil conductor laminated immediately before the second lead-out conductor.

摘要： An element body includes a principal surface arranged to constitute a mounting surface and a first side surface adjacent to the principal surface. An external electrode includes a first electrode portion disposed on the principal surface and a second electrode portion disposed on the first side surface. The first electrode portion includes a sintered metal layer, a conductive resin layer formed on the sintered metal layer, and a plating layer formed on the conductive resin layer. The second electrode portion includes a first region and a second region. The first region includes a sintered metal layer and a plating layer formed on the sintered metal layer. The second region includes a sintered metal layer, a conductive resin layer formed on the sintered metal layer, and a plating layer formed on the conductive resin layer. The second region is located closer to the principal surface than the first region.

摘要： In a multilayer coil component, a plurality of coil conductors are stacked in a coil axis direction. A connecting conductor connects the coil conductors adjacent to each other in the coil axis direction. First, second, and third coil conductors are arranged in order in the coil axis direction. A main body portion extends in a circumferential direction of the coil axis. Pad portions are connected to the main body portion, are connected to the first coil conductor via the connecting conductor, overhang from the third coil conductor in a direction away from the coil axis when viewed from the coil axis direction, and are inclined with respect to a virtual plane orthogonal to the coil axis direction.
