PROBLEM TO BE SOLVED: To provide a precoated aluminum sheet for a slot-in-drive case capable of making it hard not only to damage an optical disk upon the contact of the protruded part on the inner surface of a slot-in-drive case with the optical disk but also to emit a sound upon the contact with the edge surface of the optical disk. SOLUTION: The precoated aluminum sheet for the slot-in-drive case comprises: a coating film A with a thickness of 5-25μm, which contains at least one kind of a base resin A1 selected from the group consisting of a polyester resin, an epoxy resin and an acrylic resin and at least one kind of a lubricant A2 selected from the group consisting of carnauba wax, polyethylene wax and microcrystalline wax in an amount of 4-13 wt.%, on one chemical forming film; and the conductive resin film B, which contains a base resin B1, an Ni filler and a lubricant B2, on the other chemical forming film.
