PURPOSE:To obtain a composite sheet having soft feeling and excellent fittability, dust-proofing property, bacteria barrierness, etc., by laminating a specific nonwoven fabric or a knit or woven fabric to at least one surface of a nonwoven fabric composed of a specific ultrafine fiber. CONSTITUTION:The objective composite sheet is composed of (A) a nonwoven fabric X composed of ultrafine fibers having an average fiber diameter of <=8.0mum and (partly) containing a hydrogenated block copolymer produced by hydrogenating a block copolymer containing (i) >=2 polymer blocks composed mainly of a vinyl aromatic compound and (ii) >=2 polymer blocks composed mainly of a conjugated diene compound and having one or more components ii at the terminal of the polymer chain and (B) a nonwoven fabric or knit or woven fabric y laminated to at least one surface of the above nonwoven fabric X and composed of bonded fibers having an average fiber diameter of >=10mum. |
