The ${}^{106}\mathrm{Cd}$($\alpha ,\gamma )$${}^{110}\mathrm{Sn}$ reaction cross section has been measured in the energy range of the Gamow window for the astrophysical $p$-process scenario. The cross sections for ${}^{106}\mathrm{Cd}$($\alpha ,n$)${}^{109}\mathrm{Sn}$ and for ${}^{106}\mathrm{Cd}$($\alpha ,p$)${}^{109}\mathrm{In}$ below the ($\alpha ,n$) threshold have also been determined. The results are compared with predictions of the statistical model code NON-SMOKER using different input parameters. The comparison shows that a discrepancy for ${}^{106}\mathrm{Cd}$($\alpha ,\gamma )$${}^{110}\mathrm{Sn}$ when using the standard optical potentials can be removed with a different α + ${}^{106}\mathrm{Cd}$ potential. Some astrophysical implications are discussed.
