The momentum distribution of a charged Bose gas at high density has been figured out as the function of the reduced wave number k up to the terms of order 1/N in the 1/N-expansion method of our theory of the density-phase operator approach. In the low momentum limit, besides the well-known term which diverges as k^<-2>, it has been shown that there appears another term which diverges as k^<-1> together with several regular terms. For higher wave numbers than k=0.1 the computation has been made by follwing the Monte Carlo integration method. Remarks have been made on the condensate fraction and on the higher order terms of order 1/N^2.
