  We studied the electronic structure of PtPb$_{4}$ using laser angle-resolved
photoemission spectroscopy(ARPES) and density functional theory(DFT)
calculations. This material is closely related to PtSn$_{4}$, which exhibits
exotic topological properties such as Dirac node arcs. Fermi surface(FS) of
PtPb$_{4}$ consists of two electron pockets at the center of the Brillouin
zone(BZ) and several hole pockets around the zone boundaries. Our ARPES data
reveals significant Rashba splitting at the $\Gamma$ point in agreement with
DFT calculations. The presence of Rashba splitting may render this material of
potential interest for spintronic applications.
