<p>The present invention relates to a pre-coated aluminium plate for an electric device, which is excellent in conductivity, lubricity, anti-fingerprint capability, and scratch resistance even for packaging materials. On an original material plate (11) there is provided a composite skin film containing an inorganic component and an organic component, and the pre-coated aluminium plate (10) for the electric device is pressed on the composite skin film (12) with a resistor value below 1 ohm between a predetermined ball-shaped terminal and an aluminium original material plate (11), wherein the surface roughness Ra of the aluminium original material plate (11) is 0.3-0.5 microns, the composite skin film (12) contains a Zr component and a silicone component as the inorganic components, and comprises at least one of a polyurethane resin and a acrylic resin, the conversion adhesion amount of the Zr component is 5-500 mg/m2, the conversion adhesion amount of the silicone component is 2-600 mg/m2, the adhesion amount of the organic resin component is 5-650 mg/m2, and the total adhesion amount of ZrO2 of the Zr component is 70-700 mg/m2.</p> |
