description The present invention provides a carbon fiber bundle for filament winding, which is high in the strength conversion ratio of a raw carbon fiber thread, in other words, improved in strength of final composite materials. The present invention relates to a carbon fiber sizing agent and the carbon fiber bundle coated on the surface of the carbon fiber with the sizing agent, wherein the carbon fiber sizing agent includes: resin composed of 75-90 mass% of epoxy resin, 5-25 mass% of ester resin, and 3-5 mass% of phenoxy resin with respect to 100 mass% of resin; and 2-10 mass% of an emulsifying agent and 0.5-3 mass% of a leveling agent with respect to 100 mass% of the resin. In addition, when the carbon fiber bundle wound around a bobbin is unwound and measured, the carbon fiber bundle which has the filament number of 12,000 or more to 48,000 or less has fiber width uniformity (CV%) of 11% or lower, a fiber width maintenance rate of 80% or higher, a gap-filling ratio of 0.3 or lower, and the strength conversion ratio (%) of 85% or higher. 수지 100 질량%에 대해 에폭시 수지 75~90 질량%와 에스테르 수지 5~25 질량% 및 페녹시 수지 3~5 질량%를 포함하는 수지 100 질량%에 대해 유화제 2~10 질량% 및 평활제 0.5~3 질량%를 포함하는 탄소섬유 사이징제 및 이 사이징제를 탄소섬유 표면에 부착시킨 탄소섬유 다발에 관한 것으로, 보빈상 감긴 탄소섬유 다발을 해사하여 측정시, 사폭 균일도(CV%)가 11 % 이하이고, 사폭 유지율이 80 % 이상이며, 틈메워짐 비가 0.3 이하이고, 강도전환율(%)이 85 이상인, 필라멘트 수가 12,000 이상 ~ 48,000 개 이하인 탄소섬유 다발에 관한 것이다.
