By combining angle-resolved photoemission spectroscopy and $in$-$situ$ molecular beam epitaxy, we studied the momentum-resolved superconductivity in $\\beta$-$\\rm{Bi_2Pd}$ film. We found that the superconducting gap of topological surface state ($\\Delta_{TSS} \\sim$ 3.8 meV) is anomalously enhanced from its bulk value ($\\Delta_b \\sim$ 0.8 meV).
