On the basis of the itinerant-electron model for the 4f electrons, the energy band structure, especially the Fermi surface, is calculated for the paramagnetic heavy-electron compound CeRh_2, which has the low-temperature electronic specific heat coefficient of 20 mJ/K^2 mol and the Kondo temperature of 400 K, by a self-consistent symmetrized relativistic APW method with the exchange and correlation potential in a local-density approximation. The Fermi surface consists of two hole spheres and a hollow electron sphere with small windows, all of which are centered at the Γpoint in the Brillouin zone. The spherical property of the Fermi surface explains qualitatively well the behavior of the de Haas-van Alphen frequency branches measured recently by Sugawara et al. Candidates for the frequency branches missing in the experiment are suggested.
