PROBLEM TO BE SOLVED: To provide a porous sheet which has excellent flexibility and moldability and uses an aliphatic polyester resin as a raw material resin. SOLUTION: The porous sheet is obtained by melt-molding a resin composition comprising an aliphatic polyester resin, a filler, and a plasticizer to form a raw sheet and subjecting the raw sheet to at least monoaxial stretching, and the compounding amount of the filler is 20-300 pts.wt. based on 100 pts.wt. the aliphatic polyester resin, and the plasticizer is an aliphatic phosphoric ester, and the compounding amount of the plasticizer is 0.5-100 pts.wt. based on 100 pts.wt. the aliphatic polyester resin.
