PURPOSE: To obtain a moldable nonwoven sheet having flexural durability. CONSTITUTION: In a nonwoven sheet comprising a polyester-based filament, having 0.25g/cm<3> to 0.80g/cm<3> average apparent density and >=100% elongation at break at 150 deg.C, the nonwoven sheet has fine unevenness, 5% to 50% surface area ratio of dented parts of the unevenness and the relation between a scratching resistance value (Y for short) and a needle sticking resistance value (X for short) satisfying the conditions of the following expressions (1) or (2). The expression (1) Y/X>=5.00 when 0<X<=1.2. The expression (2) (Y-4.5)/X>1.25 when X>1.2. |
