A wet capacitor capable of helping to increase the power output of a circuit to be used and exhibiting good volumetric efficiency in terms of capacitance and capacity is provided. A wet electrolytic capacitor comprising a sintered porous anode body 22 including a dielectric layer, a liquid electrolyte, and a cathode, wherein at least one longitudinally extending channel 28 is formed in a concave shape in the anode body 22. Is done. Channel 28 has a relatively high aspect ratio (length divided by width) of about 2 or more, about 5 or more, about 10 to about 200, about 15 to about 150, about 20 to about 100, or about 30 to about 60.
