Example 1
[0079]Ten aluminum apparatuses of the present invention shown in FIG. 1 were placed in series to form a film of aluminum plating on a base body.
Base Body
[0080]As the base body, a resin formed body was used that had a three-dimensional network structure having a surface on which an aluminum film was formed by the sputtering process.
[0081]As the resin formed body having a three-dimensional network structure, a foamed-urethane resin formed body having a porosity of 95%, the number of pores (the number of cells) per inch of about 50, a pore diameter of about 550 μm, a width of 500 mm, and a thickness of 1 mm was used. Conductive treatment was performed by forming an aluminum film having a coating weight of 10 g / m2 on the foamed-urethane resin formed body by the sputtering process.
[0082]It was confirmed that an aluminum oxide film of 30 nm was formed in the aluminum film on the surface of the resin formed body.

Example
Example 2
[0095]As shown in FIG. 2, a conventional aluminum-plating apparatus was placed at the most upstream side in the conveying direction for the base body. Nine aluminum apparatuses of the present invention used in Example 1 were placed in series at the downstream side of the above-described conventional aluminum-plating apparatus to form a film of aluminum plating on a base body.
Base Body
[0096]A resin formed body having the same three-dimensional network structure as that employed in Example 1 was used.
[0097]Conductive treatment of the resin formed body was carried out by coating a carbon paint as a conductive paint on the surface of a resinous porous body. The carbon paint contained 25% carbon particles, a resin binder, an introfier, and an antifoaming agent. The carbon black had a particle diameter of 0.5 μm.

Example
Comparative Example 1
[0101]A film of aluminum plating was formed on the surface of a base body through the same procedure as that used in Example 1, except that as the aluminum-plating apparatus, 10 conventional aluminum-plating apparatuses were used by placing them in series. As for the conventional aluminum-plating apparatuses, the aluminum-plating apparatus placed at the most upstream side in Example 2 were used. As with Example 1, the space between the aluminum-plating apparatuses was filled with nitrogen to form an inert atmosphere.
[0102]Observation of the film of aluminum plating formed on the surface of the base body revealed that the deposition created the shape of islands and that the film was inferior in quality to the film formed by using the apparatus of Example 1.
