A method for manufacturing a hoisting rope (R,R',R",R"'), comprising the steps of providing a plurality of elongated composite members (1,1',1",1"'), which composite members (1,1',1",1"') are made of composite material comprising reinforcing fibers (f) in polymer matrix (m); arranging the composite members (1,1',1",1"') to form an elongated row (r,r',r",r"') of parallel composite members 1,1',1",1"', which row (r,r',r",r"') has a longitudinal direction (L), a thickness direction (T) and a width direction (W), and in which row (r,r',r",r"') the composite members (1,1',1",1"') are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction (W) of the row (r,r',r",r"'); directing plasma treatment on the outer surface of the composite members (1,1',1",1"'); embedding the composite members (1,1',1",1"') in fluid polymer material (2); and solidifying the polymer material wherein the composite members (1,1',1",1"') are embedded. A hoisting rope (R,R',R",R"') obtained with the method and an elevator comprising the hoisting rope (R,R',R",R"') are disclosed, too. The plasma treatment allows for an increased transmission ability of a hoisting rope compared to no plasma treatment.
