Provided are: an antistatic resin composition which not only has long-lasting and sufficient antistaticity and shows hardly any ion elution when made into a molded article but also is suitable for containers and packaging materials for storage and transport of electrical/electronic components; and a container and a packaging material which comprise the same.
The antistatic resin composition includes, with respect to 100 parts by mass of a synthetic resin, 3 to 20 parts by mass of at least one polymer compound (E) and 0.1 to 5 parts by mass of at least one alkali metal salt (F). The polymer compound (E) has a structure in which a diol, an aliphatic dicarboxylic acid, an aromatic dicarboxylic acid, a compound (B) which comprises at least one group represented by the following Formula (1) and has hydroxyl groups at both ends, and a compound (D) having a reactive functional group are bound via ester bonds, or ester bonds and amide bonds:
-CH2-CH2-O- (1)
