We investigate a weak electron screening effect on the electron capture of proton in the neutrino-driven wind of proto-neutron stars. Our results show that the electron screening has little influence on specific heating rate, entropy and other physical parameters in the wind. However, it improves electron fraction obviously, which strongly supports the latest nucleosynthesis of rapid neutron capture process.
