PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition for producing a porous film or sheet excellent in moisture permeability and also in flexibility and elastic recovery, and provide a porous film or sheet excellent in above- mentioned characteristics. SOLUTION: This composition contains 100 pts.wt. thermoplastic elastomer (A) consisting of at least 50 wt.% component (a) comprising an aromatic vinyl compound/conjugated diene block copolymer and/or a hydrogenated diene polymer, and 0-50 wt.% other thermoplastic polymer (b) [the total of component (a) and component (b) being 100 wt.%], and 50-400 pts.wt. filler (B). |
