Provided are a splittable conjugate fiber which is split by a weak external force about a high-pressure water column, and is split into a microfiber; and a non-woven fabric having excellent wiping properties. The splittable conjugate fiber comprises 60-90 wt% of a component A, and 10-40 wt% of a component B, wherein the component A and the component B are incompatible, the component A or the component B is an acrylonitrile polymer. The splittable conjugate fiber has the sectional shape vertical to the fiber axis of a flat shape having flattening of 3-20, inclusively, and has a conjugate structure having a sea part of the component A and an island part of the component B. The non-woven fabric formed by using the splittable conjugate fiber has a split part formed by split of the splittable conjugate fiber, wherein the split part includes a part having fiber width of 0.01-1 μm. 고압 주상 수류 정도의 약한 외력으로 할섬되고, 또한 할섬 후의 섬유가 극세인 할섬성 복합 섬유, 및 우수한 닦임성을 발휘하는 부직포를 제공한다. 성분 A 60질량% 이상 90질량% 이하, 성분 B 10질량% 이상 40질량% 이하를 포함하는 할섬성 복합 섬유로서, 성분 A와 성분 B는 비상용성이고, 성분 A 또는 성분 B가 아크릴로나이트릴계 중합체이며, 섬유축에 수직인 섬유 단면의 형상이 편평률 3 이상 20 이하의 편평 형상이고, 성분 A가 해부, 성분 B가 도부인 복합 구조를 갖는 할섬성 복합 섬유, 및 이 할섬성 복합 섬유를 이용하여 이루어지는 부직포로서, 이 할섬성 복합 섬유가 할섬되어 형성된 할섬부를 갖고, 상기 할섬부는 섬유 폭이 0.01㎛ 이상 1㎛ 이하인 부분을 갖는 부직포.
