An electric double-layer capacitor includes a plurality of electrode elements each having a current collector, a polarized electrode disposed on a surface thereof, and a strip-like current collecting lead extending from an end of the current collector. The electrode elements are stacked as alternately belonging to respective polarities, and the current collecting leads of the electrode elements are stacked into lead assemblies of the respective polarities. A separator is interposed between the stacked electrode elements, and the lead assemblies are connected respectively to electrode terminals. The lead assemblies of respective polarities serve as respective connectors connected to the electrode terminals. Each of the connectors has a flat joint region as at least a portion thereof. The current collecting leads of each of the lead assemblies are integrally joined to each other by the flat joint region by ultrasonic welding before the connector is connected to the electrode terminal. The connectors are joined to the electrode terminals, respectively, through the respective joint region by electron beam welding or laser beam welding.

In a process for molding a fiber molding for a fiber-reinforced composite material with short fibers oriented in one direction, a slurry molding material having short fibers dispersed in a liquid is used, and pressing forces are applied to the molding material from two directions substantially perpendicular to each other within a mold, while removing the liquid.

A silicon carbide-reinforced light alloy composite material comprises a matrix of a light weight alloy and a reinforcing material consisting of at least one of a silicon carbide whisker and a silicon carbide grain. In the composite material, the content of SiO.sub.2 contained in the reinforcing material, is set in the range of 0.05 to 5.0% by weight.

This invention relates to a fiber-reinforced metallic member in which an essential part is reinforced by inorganic fibers. The fiber-reinforced metallic member is reinforced by means of a fiber shaped body having a low fiber volume proportion which is formed by mixing powder having the same composition as the metal forming a non-reinforced layer thereof or powder consisting of principal components of the metal with inorganic fibers, the particle diameter of the powder being 1 to 20 times as large as a diameter of the inorganic fibers, and compressing and shaping the mixture. It is also possible to place the layer which is reinforced by the fiber shaped body having a low fiber volume proportion, adjacent to the non-reinforced layer, and to increase a fiber volume proportion in the reinforced layer in the direction of separating from the adjacent reinforced layer. By employing such structure, it is possible to eliminate abrupt change of the characteristics of the materials at the boundary portion between the complex reinforced layer and the non-reinforced layer and to provide a structural member having a good durability.
