We performed polarization- and photon-energy-dependent angle-resolvedphotoemission spectroscopy of a slightly overdoped iron pnictidesuperconductor, BaFe$_{1.8}$Co$_{0.2}$As$_{2}$, to clarify thethree-dimensional electronic structure including its orbital characters at theBrillouin zone center. Two hole Fermi surfaces (FSs) with $d_{xz/yz}$ and$d_{xy/x^2-y^2}$ orbitals were observed but $d_{z^2}$ hole FS, which has nodesaccording to a theory of the spin-fluctuation superconductivity mechanism, didnot appear. These results suggest that no node will appear at hole FSs at thezone center.
