PROBLEM TO BE SOLVED: To provide a method for producing an electroconductive acrylic fiber having an excellent electroconductivity and excellent whiteness by a wet spinning method in a higher productivity stably. SOLUTION: This method for producing the electroconductive acrylic fiber consisting of an acrylic polymer as a main component and having a sheath core structure containing electroconductive fine particles in its core part is provided by using organic solvent solution dissolving the acrylic polymer with the organic solvent as a spinning stock solution of the sheath component and also organic solvent solution dissolving by mixing the electroconductive fine particles (A) and the acrylic polymer (B) so as to become 4-20 weight ratio of the (A)/(B) as the spinning solution of the core component, spinning by setting the viscosity of spinning stock solution of the sheath component as≤300 poise, and setting the sheath core ratio so that the content the electroconductive fine particles contained in the electroconductive acrylic fiber becomes 5-15 wt.% by using a sheath core type spinneret, and then performing 30-50% thermal shrinkage treatment.
