The present invention relates to an acrylic fiber for artificial hair that includes an acrylic polymer. The acrylic polymer contains 29.5 to 79.5% by mass of acrylonitrile, 20 to 70% by mass of vinyl chloride and/or vinylidene chloride, and 0.5 to 5% by mass of a sulfonic acid group-containing vinyl monomer. The acrylic fiber for artificial hair includes 0.3 to 2% by mass of a good solvent for the acrylic polymer and 0.1 to 5% by mass of an epoxy group-containing compound.
