A container for precision substrate having one or more component formed by molding a thermoplastic resin, characterized in that the 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&#xb0; 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 cmof the component. [2] When being placed in the air at 100&#xb0; C., an increase amount of organics in the air in 300 minutes is 150 ng or less per weight 1 g of the component. According to the container, demands for low contamination can be satisfied.

Container for precision substrate

A resin mold for molding a curable resin, which has been made by molding a resin composition comprising an alicyclic structure-containing polymer and a nitrogen-containing organic compound (X) having at least one nitrogen atom which is bonded to at least one tertiary or quaternary carbon atom. A curable resin is molded and cured using a combined mold which is a combination of two resin molds (A) and (B), wherein at least one (A) of the two resin molds is made by molding a resin composition comprising an alicyclic structure-containing polymer and the nitrogen-containing organic compound (X). Preferably, the two molds (A) and (B) are made by molding resin compositions comprising an alicyclic structure-containing polymer and different amounts of the nitrogen-containing organic compound (X).
