The present invention relates to a method for producing a carbon nanotube fiber aggregate. According to the present invention, by applying ultrasonic waves and adding a crosslinking agent, it is possible to obtain the carbon nanotube fiber aggregate having enhanced interfiber attraction. To this end, the method comprises the following steps: immersing the carbon nanotube fibers in a solution containing the crosslinking agent; and applying ultrasonic waves to the immersed carbon nanotube fibers. 본 발명은 탄소나노튜브 섬유 집합체 제조 방법에 관한 것으로서, 초음파 인가 및 가교제 첨가를 통해 섬유간 인력이 향상된 탄소나노튜브 섬유 집합체를 얻을 수 있다.
