This paper reports measurement results of instrumental analyses, permittivity, conduction current, and space charge distribution profiles observed in low-density polyethylene/MgO nanocomposites with various filler contents, done with the intention to clarify the filler-content dependence of dielectric properties. The permittivity shows the lowest value in the sample with 1-phr fillers and then increases monotonically with an increase in filler content. The conductivity measured under dc electric field lowers by the filler addition up to 5 phr at temperatures from 5 to 90°C. In all the samples, positive homocharge is formed in the vicinity of the anode, and its amount is largest at 1 phr. The most adequate filler content for the electrical insulation purpose is around 1 to 5 phr.
