PROBLEM TO BE SOLVED: To provide a molded antistatic resin article having low resistivity by an inexpensive simple method without using an additive. SOLUTION: The molded antistatic polyester amide resin article is produced by the copolymerization of (a) a cyclic amide and at least one kind of ester selected from (b<SB>1</SB>) a cyclic ester and (b<SB>2</SB>) at least one kind of chain ester selected from the group consisting of a polyester polyol, a polyester ether polyol and a polycarbonate polyol, and has a surface resistivity of <10<SP>13</SP>Ω.
