The angle-resolved photoemission from high-T_c superconductors is 
discussed, and the model of the rescattering of photoelectrons is 
proposed. It is shown that the rescattering process in the 
superconducting state is rather different from that of in the normal 
state, what thus leads to the features which are generally observed in 
the experiments.
