PROBLEM TO BE SOLVED: To obtain a workpiece of a polyimide laminated body on which punching processing, cutting processing, drilling processing, notching processing, etching processing, grinding processing, plating processing, bending processing and drawing processing can be easily performed and which exhibits excellent heat resistance.;SOLUTION: A base material, e.g. a metal sheet, a metal foil, a heat-resistant resin sheet such as a polyimide, a PEEK film and a polyimide, the said films and an inorganic base material such as a silicon wafer is coated with a polyimide obtained by polycondensation of at least one ingredient of alicyclic diamines of the below described formula (1) ( wherein aminomethyl groups are bonded at the positions 2 and 5 or at the positions 2 and 6) with tetracarboxylic acid dianhydride of the below described formula (2) (wherein W is a tetravalent organic group). A workpiece and a secondary workpiece are obtained by using the metal sheet.;COPYRIGHT: (C)2002,JPO
