We investigated the electronic structure of the antiferromagnetic Kondo lattice ${\mathrm{CePd}}_5{\mathrm{Al}}_2$ using high-resolution angle-resolved photoemission spectroscopy. The experimentally determined band structure of the conduction electrons is predominated by the Pd $4d$ character. It contains multiple hole and electron Fermi pockets, in good agreement with density functional theory calculations. The Fermi surface is folded over ${\mathit{Q}}_0=(0,0,1)$, manifested by Fermi surface reconstruction and band folding. Our results suggest that Fermi surface nesting drives the formation of antiferromagnetic order in ${\mathrm{CePd}}_5{\mathrm{Al}}_2$.
