PROBLEM TO BE SOLVED: To provide a polyvinyl alcohol-based fiber having all of practically sufficient mechanical characteristics, heat resistance and electroconductive performance, applicable to fabrics such as paper, a nonwoven fabric, a woven fabric and a knit fabric and much useful for several uses such as a charging material, a discharging material, a brush, a sensor, an electromagnetic wave shielding material and an electronic material, and to provide a method for producing the fiber. SOLUTION: The polyvinyl alcohol-based fiber comprises a polyvinyl alcohol-based polymer, and copper sulfide nanoparticulates finely dispersed in the polymer and having≤100 nm average particle diameter, wherein the polyvinyl alcohol-based fiber has continuous convex parts continuing in the fiber axis direction and continuous recessed parts continuing in the fiber axis direction, on the fiber surface by turns.
