ABSTRACT Disclosed is a method of and apparatus for making capacitors, the capacitors each comprising a plurality of layers having opposed edges, each layer comprising a dielectric substrate and a metallic film, the metallic film extending from one edge toward the other edge. Each layer includes a zone free of the metallic film, the zone being adjacent to but spaced from the other edge to leave a narrow marginal metal film band at the other edge which is spaced by the zone from the remainder of the metallc film. The layers are disposed with the metal film of one layer being separated by dielectric material from the metal film of the adjacent layer, the layers being offset such that at one side of the capacitor the edges of a first group of layers lie outwardly beyond the other edges of a second group of layers. At the opposite side of the capacitor the edges of the second group of layers lie outwardly beyond the other edges of the first group of layers. The layers in the first group alternate with the layers of the second group and the outwardly lying edges of the layers in each group are coated with electrically conductive material to connect electri- cally the metal film layers of each group.
