We study theoretically the anisotropic magneto-Peltier effect, which was recently demonstrated experimentally. A first-principles-based Boltzmann transport approach including the spin-orbit interaction shows that Ni has a larger anisotropy of the Peltier coefficient ($\mathrm{\ensuremath{\Delta}}\mathrm{\ensuremath{\Pi}}$) than Fe, consistent with experiments. It is clarified that spin-flip electron transitions due to the spin-orbit interaction are the key in the mechanism of the large anisotropic magneto-Peltier effect. Using our method, we further predict several ferromagnetic metals with much larger $\mathrm{\ensuremath{\Delta}}\mathrm{\ensuremath{\Pi}}$ than that of Ni.
