The ground-state electronic structure of a small spherical metal shell is investigated on the basis of the model system composed of valence electrons and a spherical jellium shell (JS). The electron density distribution and the effective one-particle potential are calculated by means of the density functional theory involving the local density approximation. We follow the evolution of the electronic structure as we vary the electron number and the inside radius of the JS, conserving the charge neutrality as a whole. The results of our calculation highlight the characteristics of the electronic structure of the small spherical metal shell, which can be understood in terms of the transition from the electronic structure of the metal sphere to that of the electron system sharply localized around a spherical surface.
