PROBLEM TO BE SOLVED: To provide products such as stationeries using a rubber molded article in which the fear of generation of the allergic symptom is as small as possible.;SOLUTION: The rubber molded article is not made from a sap of rubber tree such as natural rubber as usual, but made from an extract which is extracted from polyisoprene in spruce milk cap, thereby the rubber molded article does not include protein which causes the allergic symptom and there is no possibility of the generation of the allergic symptom. And such rubber molded articles can be used for stationery such as a ballpoint pen and an office supply.;COPYRIGHT: (C)2006,JPO&NCIPI
