PROBLEM TO BE SOLVED: To obtain a safe heat-resistant antistatic agent not dangerous when heated, and having excellent heat resistance by mixing a boron complex lithium salt having a specific structure with an organic polymer. SOLUTION: This heat-resistant antistatic agent comprises (A) a boron complex lithium salt of formula I (R1 is H, a 1-4C alkyl or the like; R2 is a substituted or non-substituted benzene ring or naphthalene ring) and (B) an organic polymer having a comb type structure which has polyether segments on side chains and is expressed by formula II or III [R3 is a polyether segment; R4, R5 are each H or methyl; (l), (m) and (n) are each a positive integer]. The polyether segment of the component B includes polyethylene oxide. The molar number of the minimum polyether segment repeated units is preferably 3-18, and the mol fraction of the minimum units is preferably 0.2-0.8. The content of the component A in the antistatic agent is preferably 0.1-2.2 moles/kg.
