Abstract
Provided are an electrically conductive layer coated aluminum material having properties which can withstand long term use; and a method for manufacturing the electrically conductive layer coated aluminum material. The electrically conductive layer coated aluminum material includes: an aluminum material (1); a first electrically conductive layer (2); an interposing layer (3); and a second electrically conductive layer (4). The first electrically conductive layer (2) is formed on a surface of the aluminum material (1) and includes an organic substance having electrical conductivity. The interposing layer (3) is formed between the aluminum material (1) and the first electrically conductive layer (2) and includes a carbide of aluminum. The second electrically conductive layer (4) is formed on a surface of the first electrically conductive layer (2) and includes carbon-containing particles (41). A resin is attached onto the surface of the aluminum material (1) and is dried, a carbon-containing substance is attached thereonto, and thereafter, the aluminum material (1) is placed in a space including a hydrocarbon-containing substance and is heated, thereby forming the first electrically conductive layer (2), the interposing layer (3), and the second electrically conductive layer (4).
