The hidden conformal symmetry of extreme and non-extremeEinstein-Maxwell-Dilaton-Axion (EMDA) black holes is addressed in this paper.For the non-extreme one, employing the wave equation of massless scalars, theconformal symmetry with left temperature $T_{L}=\frac{M}{2\pi a}$ and righttemperature $T_{R}=\frac{\sqrt{M^{2}-a^{2}}}{2\pi a}$ in the near region isfound. The conformal symmetry is spontaneously broken due to the periodicity ofthe azimuthal angle. The microscopic entropy is derived by the Cardy formulaand is fully in consistence with the Bekenstein-Hawking area-entropy law. Theabsorption cross section in the near region is calculated and exactly equalsthat in a 2D CFT. For the extreme case, by redefining the conformalcoordinates, the duality between the solution space and CFT is studied. Themicroscopic entropy is found to exactly agree with the area-entropy law.
