PROBLEM TO BE SOLVED: To provide a carbon fiber bundle in which a convergence property of a carbon fiber, openability in an aqueous dispersion medium, and conservation of the openability after water dispersion are excellent, and that is suitable to aqueous processing.SOLUTION: Provided is a carbon fiber bundle for aqueous processing that includes a carbon fiber and a siding agent, and the carbon fiber bundle for aqueous processing is that the siding agent is a polyamide that at least includes: an amino carboxylic acid unit; a dicarboxylic acid unit; and a polyether diamine unit, a chemical formula amount of a polyether structure in the polyether diamine unit is at least 100 and at most 3,000, the amino carboxylic acid unit is 20-30 mol%, and the sum of the dicarboxylic acid unit and the polyether diamine unit is 70-80 mol%. |
