Introducing an H-Hopf algebroid structure into U q,p (Sl 2 ), we investigate the vertex operators of the elliptic quantum group U q,p (Sl 2 ) defined as intertwining operators of infinite dimensional U q,p (Sl 2 ) modules. We show that the vertex operators coincide with the previous results obtained indirectly by using the quasi-Hopf algebra L3q ,x (S[ 2 ). This shows a consistency of our H-Hopf algebroid structure even in the case with a nonzero central element.
