The invention provides a precoating aluminum plate for an electronic device, the precoating aluminum plate is advantaged by excellent conductivity, lubrication, fingerprint resistance, flaw resistance, and corrosion resistance, as well as suitable environmental protection. A precoating aluminum plate (10) is characterized in that, a substrate processing film containing chromium is not disposed on at least one surface of an aluminum blank (11) with an arithmetic average roughness Ra of 0.3 microns to 0.5 microns, and a resin film (12) is formed, the resin film (12) does not comprise metallic elements, but comprises an acrylic resin ingredient, an polyurethane resin ingredient, a silica ingredient and a particle-shaped lubrication ingredient, content of the silica ingredient takes up more than 12 mass% of the resin film (12), content of the lubrication ingredient contained in the resin film (12) takes up more than 8 mass %, average film thickness of the resin film (12) is 0.15 microns to 1.0 microns, and a resistance measured via a particular method is below 10 Omega. |
