The present invention relates to a hollow porous membrane having a porous membrane layer and a support body, the porous membrane layer comprising a thermoplastic resin, and the support body being obtained by processing a thread having a stretch elongation rate of 1.0% or less into a cylinder shape. Through the present invention, it is possible to provide a hollow porous membrane capable of maintaining adequate physical strength and favorable water permeating performance despite having a small outside diameter. |
