We analyze the Suzaku XIS data of the central region of supernova remnantG332.5-5.6. The X-ray data are well described by a single non-equilibriumionization thermal model, {\tt vnei}, with an absorbing hydrogen column densityof 1.4$^{+0.4}_{-0.1}$ $\times$ 10$^{21}$ cm$^{-2}$. The plasma ischaracterized by an electron temperature of 0.49$^{+0.08}_{-0.06}$ keV withsubsolar abundances for O (0.58$^{+0.06}_{-0.05}$ solar value) and Fe(0.72$^{+0.06}_{-0.05}$ solar value) and slightly overabundance for Mg(1.23$^{+0.14}_{-0.14}$ solar value). It seems that the central X-ray emissionoriginates from projection effect or evaporation of residual clouds insideG332.5-5.6. We estimate a distance of 3.0 $\pm$ 0.8 kpc for G332.5-5.6 based onthe extinction-distance relation. G332.5-5.6 has an age of 7 - 9 kyr.
