We analyse the Suzaku X-ray Imaging Spectrometer data of the central region of supernova remnant G332.5-5.6. The X-ray data are well described by a single non-equilibrium ionization thermal model, vnei, with an absorbing hydrogen column density of 1.4^+0.4_-0.1x10²¹/ cm2. The plasma is characterized by an electron temperature of 0.49^+0.08_-0.06 keV with subsolar 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 emission originates from a projection effect or evaporation of residual clouds inside G332.5-5.6. We estimate a distance of 3.0±0.8 kpc for G332.5-5.6 based on the extinction-distance relation. G332.5-5.6 has an age of 7-9 kyr.
