This paper deals with electric conduction and space charge in ethylene-vinylacetate copolymer (EVA). Conduction current and space charge in EVA films, which have electrode of different metals, were measured. From conduction current measurement, it was considered that conduction mechanism in EVA film depend on the hopping conduction mechanism in the high electric field resrion. It was also considered that magnitude of conduction current under low electric field region was decided by electrode metal. Under high electric field region, magnitude of conduction current was different against low electric field region. Electric field on the electrode was calculated from space charge distribution to compare with conduction current under high electric field region. However, there is not correlation between magnitude of conduction current and electric field on the electrode. It was suggested that electric conduction under high electric field region was decide by other mechanism containing space charge effect
