Abstract
A container for precision members is prepared from a polycarbonate resin, wherein a polycarbonate resin solution prepared by immersing the polycarbonate resin in water and leaving the solution has chloride ions (Cl), fluoride ions (F) and sulfate ions (SO) in a concentration of about 2 ppb or less, independently of each other, as detected by ion chromatography (IC). The container for precision members is capable of preserving and transporting the precision members predisposed to damage by minor amounts of impurities or contaminants without damage.
