Abstract	The efficiency of the energy conversion rate in the relativistic magnetic reconnection is investigated by means of Relativistic Resistive Magnetohydrodynamic (R2MHD) simulations. We confirmed that the simple Sweet-Parker type magnetic reconnection is a slow process for the energy conversion as theoretically predicted by Lyubarsky (2005). After the Sweet-Parker regime, we observed a growth of the secondary tearing mode in the elongated current sheet. Then the energy conversion rate and the outflow velocity of reconnection jet are rapidly increased. Next, we extend our R2MHD code to R3MHD code by including radiation effects (Relativistic Resistive Radiation Magnetohydrodynamics R3MHD), to construct a more realistic model of relativistic reconnection. We found that the radiation energy is confined within a narrow angle of the outflow exhaust due to the electron scattering. The gas is dragged by the radiation, leading to a slower outflow than that without the radiation. The resulting reconnection rate is smaller to attain the mass conservation between the inflow and the outflow.
