Aiming at the low-energy reaction and Gamow-Teller resonant transition, the influence of electron screening on the β-decay rate in stellar interior is investigated in this paper. As an example, the effect of the screening on β-decay by 56Cr is calculated. It is shown that the screening increases the β-decay rate evidently in lower temperatures and higher densities. The screening effect may importantly influence the study of stellar late stage evolution and supernova burst.
