[PROBLEMS] To provide a valve-acting metal sintered body for an anode of a solid electrolytic capacitor having a high capacity, an excellent cathode agent impregnation property, and particularly excellent physical properties when the volume is increased, and a low-ESR and tan δ characteristic and a long-term Providing reliable solid electrolytic capacitors. At least one primary powder, secondary agglomerated powder or granulated powder thereof selected from a valve action metal, a valve action metal compound and a valve action metal alloy, a pore forming agent, an organic binder, A step of applying, printing, and molding a dispersion containing a solvent, or a step of compressing and molding a granulated mixture obtained by removing the solvent of this dispersion, sintering the molded body, and forming a pore A method for producing a valve-acting metal sintered body for an anode of a solid electrolytic capacitor having a step of forming a sintered body including a step of removing a pore-forming agent contained in the sintered body, and the method Solid electrolytic capacitor using a sintered valve action metal.
