The energy band structure of a quasi one-dimensional cuprate SrCuO2 is studied by angle-resolved photoemission spectroscopy and the linear augmented-plane-wave band structure calculation within local density approximation. It was found that the band structure has strongly one-dimensional nature with a finite dispersion along the Cu-O chains. The calculated band structure of SrCuO2 is in good agreement with the angle-resolved photoemission result except for the region near the Fermi level.
