<P>PROBLEM TO BE SOLVED: To obtain a key top for a personal digital assistant superior in transparency, shock resistance, stroke intensity and productivity, and with thickness and weight reduced. Ž<P>SOLUTION: The key top for a personal digital assistant is made by forming a resin composition having resin constituent which uses 35 to 85% by weight of straight-chain polycarbonate resin (A) with viscosity average molecular weight of 14000 to 18000, and 15 to 65% by weight of branched polycarbonate resin (B) as indispensable constituent. As a result, the key top for a personal digital assistant has excellent transparency, shock resistance, stroke intensity and productivity. Thus it can be suitably used as the key top for a personal digital assistant which requires thickness reduction and weight reduction. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
