Abstract
The invention provides a hollow fiber membrane exhibiting a favorable gas permeation performance and an excellent heat resistance in which the generation of pinholes are suppressed, and a hollow fiber membrane module using the same. The hollow fiber membrane comprising a gas permeable nonporous layer; and a porous supporting layer to support the nonporous layer formed of a thermoplastic elastomer having a DSC melting peak temperature of 130° C. or higher and a rupture elongation prescribed in ISO 37 (2010) of 300% or more.
