Abell 3391/3395 is a pair of galaxy clusters at z=0.05. The clusters A3391, A3395, and a galaxy group located between the two clusters are in alignment along a large-scale filament. The previous studies by ASCA, ROSAT, Planck, Suzaku, and Chandra indicate and confirm that A3395 and A3391 are connected by the filament with hot diffuse gas. The eROSITA first-light observation of A3391/95 has been conducted, whose deepest X-ray data enable us to constrain the properties of warm (~2e6 K) and hot gas components in the filament. In this presentation, we report early results of spectral and image analyses of the filament region.
