Abstract:
1. A container for precision substrate having one or more components formed by molding a thermoplastic resin, wherein the thermoplastic resin is a polymer resin containing alicyclic structure, and the polymer resin containing alicyclic structure has a melt index of 2 to 100 g/10 min., and the melt index is a value measured at 280° C. based on the JIS-K7210, characterized in that said component satisfies characteristics [1] and [2] below: [1] When being brought to contact ultra high purity argon gas (impurity concentration: 1 ppb or less) at 25° C. having a flow rate of 1.2 L/min., a water amount in said argon gas after 300 minutes is 30 ppb or less per a surface area 1 cm [2] When being placed in the air at 100° C., an increase in the amount of organics in the air in 300 minutes is 150 ng or less per weight 1 g of the component.
