ABSTRACT OF THE DISCLOSURE An adsorptive fiber sheet where a nonwoven fabic of synthetic fiber constituted only by synthetic fiber having a higher melting temperature is secured in a layered structure to at least one surface of a nonwoven fabric of adsorptive fiber which is produced in such a manner that synthetic fiber having a higher melting temperature, synthetic fiber having a lower melting temperature and adsorptive fiber are mixed with one another and contact points between the synthetic fiber having a lower melting temperature and other fibers are bound together by softening the synthetic fiber having a lower melting temperature . Both the synthetic fabrics are placed one above another in a layered structure by allowing synthetic fiber having a lower melting temperature to be softened to bind or by allowing fibers to be entangled with one another in such a manner that no separation takes place therebetween.
