In particular, wind-blown bubbles created by the steller wind of massive stars will have significant effect on supernova remnants in that bubbles. Although these remnants are difficult to be observed because of their low X-ray brightness and the contamination by surrounding HII regions, the Einstein satellite detected several supernova remnants in the giant HII regions in the Magellanic Clouds. We propose the first hard X-ray spectroscopy of supernova remnants clearly associated with the wind-blown super bubbles in the Small Magellanic Cloud.
