Abstract:
The present invention relates to a hollow fiber membrane. Provided is a cylindrical hollow fiber membrane having an inside in which a hollow part is formed along an axial direction, the hollow fiber membrane including: a first layer positioned at the outermost part so as to be exposed to the outside, and having pores formed therein to make raw water enter and leave via the pores; a second layer formed on the inside of the first layer to filter out contaminants from raw water as the raw water passes through; and a third layer to optionally separate or filter out contaminants from the raw water introduced through the second layer or introduced from the hollow part, wherein the first layer to the third layer are integrally formed; the porosity of the first layer is greater than the porosity of the third layer; and porosities are gradually decreased from the first layer to the third layer.
