摘要： A tantalum capacitor includes a sintered tantalum body including tantalum powder, a conductive polymer layer disposed on the sintered tantalum body and including a first filler, a carbon layer disposed on the conductive polymer layer; and a tantalum body including a tantalum wire penetrating through at least a portion of each of the sintered tantalum body and the conductive polymer layer in a first direction. A ratio of an area of the first filler to an area of the conductive polymer layer is greater than 0.38 in a first cross-section partially overlapping the sintered tantalum body, among cross-sections perpendicular to the first direction.
