PROBLEM TO BE SOLVED: To provide a flexible nonwoven fabric having uniform formation and flexibility. SOLUTION: The flexible nonwoven fabric is a nonwoven fabric having 15-150 g/m<SP>2</SP>basis weight, comprising ultrafine polyester fibers A composed of a polyester, and having 500-1,000 nm single fiber diameter (D) in the ratio (L/D) of the fiber length (L) nm to the single fiber diameter (D) nm within the range of 600-3,000, and polyester fibers B having 0.05-0.6 dtex single fiber fineness and 3-20 mm fiber length in (1/99) to (50/50) weight ratio of the former/latter. The bending resistance measured by JIS L1096 6. 19. 1A method (45°cantilever method) is within the range of 2-6 cm. COPYRIGHT: (C)2009,JPO&INPIT
