  Many efforts have been devoted to the studies of the phenomenology in
particle physics with extra dimensions. We propose the degenerate fermion star
in the five dimensions, and study what effects caused by the geometry of extra
dimensions should appear in its structure. We note that Kaluza-Klein excited
modes have effects for the larger scale of extra dimensions and examine the
conditions on which different layers should be caused in the inside of the
stars. We expound how the effects of the extra dimensions appears on physical
quantities.
