PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electrolytic capacitor in which the problem that residual stress is generated in an anode body through grooving at a specified position thereof and twist or warp takes place in the anode body at the grooved part. SOLUTION: Since a plurality of through holes 2a are formed linearly at constant intervals at specified positions of an anode body 2, and linear grooves are formed symmetrically on the surface and rear by pressing specified positions of the anode body including the through holes 2a from the surface and rear, the generation of residual stress in the anode body is retarded and the grooved part is not twisted nor warped, thus realizing stabilization of production while enhancing the production efficiency and stabilizing the quality.
