PROBLEM TO BE SOLVED: To provide an antistatic agent for imparting excellent permanent antistatic properties to a thermoplastic resin, and an antistatic resin composition containing the antistatic agent having excellent moldability in a wide range of molding temperatures. SOLUTION: A block of polyolefin (a) and a volume resistivity value of 1 × 10 5 to 1 × A block polymer in which a block of a hydrophilic polymer (b) of 10 11 Ω · cm is repeatedly bonded via at least one bond selected from the group consisting of an ester bond, an amide bond, an ether bond, an imide bond and a urethane bond ( An antistatic agent comprising A), having a melt flow rate (g / 10 min, 190 ° C.) of 0.5 to 150 and a melting point of 50 to 130 ° C. by differential scanning calorimetry.
