PROBLEM TO BE SOLVED: To provide a electroconductive acrylic synthetic fiber multifilament thread having small monofilament fineness and integrally having excellent electroconductivity, fibrillation properties, durability and the like. SOLUTION: The electroconductive acrylic synthetic fiber multifilament has 10-800 dtex fineness, 0.1-2.0 dtex monofilament fineness and characteristics described by following items (1) and (2): (1) the fiber forming polymer comprises an acrylonitrile-based polymer and the antistatic polymer comprises a copolymer of a polyalkylene glycol with acrylonitrile and (2) the antistatic polymer contains carbon black. In the multifilament, an antistatic polymer constituting the electroconductive part in each of the filaments is distributed in a fibril form and a network structural form in a fiber forming polymer constituting a nonelectroconductive part.
