The diffuse X-ray emission, which are associated with the eastern  and western radio lobes, were observed in a 0.7--7 keV Chandra$ ACIS image. The lobe spectra are reproduced with not only a single-temperature Mekal model, such as that of the surrounding ICM component, but also an additional power-law (PL) model. The X-ray flux densities of PL components for the eastern and western lobes at 1 keV are derived as 77.7^{+28.9}_{-","authors_text":"H. Nagai, K. Asada, M. Kino, M. Kusunose, M. S. Tashiro, N.
