As a nonwoven fabric having little absorption of a volatile low molecular weight compound, it provides a nonwoven fabric having good texture when it is a nonwoven fabric used for human skin. Glass transition point Tg A1 ℃ of the cyclic olefin-based fiber (A) the resin containing at least 50% by weight of (A1), and a glass transition point of the cyclic olefin-based resin (B1) of Tg B1 ℃, or the melting point of crystals of Mp B2 ℃ Castle the thermoplastic resin fibers containing (B2) for at least 10 mass% (B), to include at least, and the fibers (a) and the fibers (B) is a thermal-bonded nonwoven fabric containing the cyclic olefin based resin which is heat-sealed, Tg A1> Tg B1 or Tg A1 & gt ; Mp B2 , and the difference between the glass transition point Tg A1 DEG C and the glass transition temperature Tg B1 DEG C, or the difference between the glass transition point Tg A1 DEG C and the melting point Mp B2 DEG C exceeds 20 DEG C, It is a thermal bond nonwoven fabric. |
