We reexamine the non-additive entropy which was first proposed by Tsallis  where this deformed entropy (q-entropy) is related to a special map. We consider a new map giving the -additive property. Based on this, we propose a new type of non-additive entropy which we call -entropy and derive the -deformed Boltzmann factor and -deformed free energy. As an example, we discuss the black body radiation in the -deformed thermodynamics where we regard photon as a particle obeying -deformed boson algebra.
