The advance of neutron physics are reviewed from the viewpoints of fundamental characteristics of neutron and conservation laws and interactions of neutrons with nuclei. The newest experimental results of weak interaction constants defined in neutron decay and neutron electrical dipole moment are given. The mechanism of P violation and possible
