Abstract

Disclosed is a carbon fiber precursor treatment agent that contains a specific (poly)oxyalkylene derivative and a smoothing agent. The smoothing agent contains at least one selected from the group consisting of an amino-modified silicone, a polyether-modified silicone, a dimethyl silicone, and an ester compound. Assuming that the sum of the content ratios of the (poly)oxyalkylene derivative and the smoothing agent in the carbon fiber precursor treatment agent is 100% by mass, the carbon fiber precursor treatment agent contains the (poly)oxyalkylene derivative at a ratio of 5% by mass or more and 80% by mass or less and the smoothing agent at a ratio of 20% by mass or more and 95% by mass or less.
