Abstract: The jet function for the factorized cross section ${e}^{+}{e}^{\ensuremath{-}}$ into dijets is given as a function of the jet invariant mass $s$ and with a generic jet algorithm at $\mathcal{O}({\ensuremath{\alpha}}_{s})$. We demonstrate the results using the Sterman-Weinberg algorithm and show that the jet function is independent of the energy fraction $\ensuremath{\beta}$ of the soft radiation. The anomalous dimension has the same form with and without the cone half-angle $\ensuremath{\delta}$. The dependence of the finite part of the jet function on the cone angle is given.
