<P>PROBLEM TO BE SOLVED: To provide a laminate that is made by bonding the polyolefin nonwoven fabric and the polyether sulfone resin porous film without using adhesives, wherein the nonwoven fabric and the porous film are strongly bonded without oozing out of the foreign objects and the residual solvent, etc., and without deteriorating the original performance of the nonwoven fabric and the porous film. <P>SOLUTION: The polyolefin nonwoven fabric and the polyether sulfone resin porous film are bonded without the adhesives, since in at least a portion of the polyolefin nonwoven fabric and the polyether sulfone resin porous film, bonding is formed between the atom of the polyolefin nonwoven fabric and the atom of the polyether sulfone resin porous film. <P>COPYRIGHT: (C)2012,JPO&INPIT |
