Abstract:
An anode member for a solid electrolytic capacitor, said anode member comprising:a thin plate of a valve metals; and a layered sintered member formed on said thin plate and obtained by forming a layer of a valve metal powder as a material powder to be sintered and then sintering said powder layer, wherein said layered sintered member has a multi-layer structure comprising a plurality of sintered layers different in material powder and different in sintered condition; wherein said sintered layers of the layered sintered member comprise a heavily sintered layer and a lightly sintered layer as a lower layer and an upper layer, respectively; and wherein said lower layer is nearer to said thin plate than to said upper layer, and said heavily sintered layer has a thickness less than a thickness of said lightly sintered layer.
