AN ALUMINIUM PLATE HAVING A FILM AND AN ELECTRONIC DEVICE MEMBER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an aluminum sheet for electronic equipment, which is superior in fingerprint resistance and scratch resistance as well as in electroconductivity, heat-radiating characteristics and formability, and to provide a molded article using it. SOLUTION: The aluminum sheet 1 has a corrosion resistant film 3 and a resin film 4 sequentially formed from an aluminum base sheet 2 side on at least one side of the base sheet 2 having an arithmetical mean roughness Ra of 0.2-0.6μm, wherein the corrosion resistant film 3 contains Cr or Zr and has a coating weight of 10-50 mg/m2in Cr or Zr terms; the resin film 4 has an average film thickness of 0.05-0.3μm, and contains a lubricant of 1-25 mass% with respect to a total resin-coating amount; and the surface of the aluminum base sheet 2 or the corrosion resistant film 3 formed thereon, has such fine projections exposed outside the surface of the resin coating 4 that a surface resistance value between a spherical terminal with a radius of 10 mm and the aluminum base sheet 2 is 1Ωor less, when the surface on the resin coating 4 side is pressed with the spherical terminal at a load of 0.4 N.
