ABSTRACT:
A method for making a solid electrolytic capacitor including a flat porous body is provided. This method utilizes a mold which includes a horizontal surface and four vertical side surfaces. The horizontal surface and the side surfaces define a cavity into which powder made of valve metal is loaded. By compacting the powder in the cavity, a flat porous body having a predetermined thickness is formed. In the compacting, the powder is compressed vertically with the four side surfaces fixed in position.
