We investigate the gravitational field of static perfect-fluid in the presence of electric field. We adopt the equation of state for the fluid in order to consider the closed () or the open () background spatial topology. Depending on the scales of the mass, spatial-curvature and charge parameters (K, , Q), there are several types of solutions in and classes. Out of them, the most interesting solution is the Reisner–Norström type of black hole. Due to the electric field, there are two horizons in the geometry. There exists a curvature singularity inside the inner horizon as usual. In addition, there exists a naked singularity at the antipodal point in outside the outer horizon due to the fluid. Both of the singularities can be accessed only by radial null rays.
