Abstract: We investigate the vertex operators of the supergravity multiplet inIIBIKKT matrix model by calculating the disk amplitudes, exploiting thetechnique of conformal field theory. The vertex operators of IIB matrix modelare given as the coupling of a closed string and open strings which areintroduced by the existence of D-1-branes. We consider the most genericcouplings which involve both the bosonic and fermionic open strings. Ourresults are consistent with the previous results based on supersymmetry. Wethus confirm the structure of the IIB matrix model vertex operators from thefirst principle.
