Abstract

The object of the present invention is to provide an antistatic agent that imparts excellent antistatic properties to thermoplastic resins. [Solution] An antistatic agent (Z) comprising a block polymer (A) having a block of hydrophobic polymer (a) and a block of hydrophilic polymer (b) as constituent units, wherein the hydrophobic polymer (a) consists of polyolefin (a2) and polyamide (a1), and the polyamide (a1) consists of at least two constituent monomers selected from the group consisting of lactam (a101) having 4 to 20 carbon atoms and aminocarboxylic acid (a102) having 2 to 12 carbon atoms.
