<p>PROBLEM TO BE SOLVED: To provide a method for forming a capacitor element and a forming device by which the reliability can be improved without generating any damage such as breaking of a foil or cracking, etc., when the capacitor element is formed. SOLUTION: A compression force is given to a cylindrically formed capacitor element (12) so as to form the capacitor element (12) from the outer circumferential side, and at the same time, a distance between a plurality of forming guides (16 and 18) which are inserted into the hollow (14) of the capacitor element is enlarged so as to form the capacitor element (12) from the hollow side. Such combined steps can protect the capacitor element from damage such as breaking of a foil or cracking due to flattening of the capacitor element, and improve the reliability of the product.</p> |
