GRB 041006 was detected by HETE-2 at 12:18:08 UT on 06 October 2004. The GRB shows a soft X-ray emission, a precursor before the onset of the main GRB, and also shows a soft X-ray tail after the end of the main peak. The light curves within four different energy bands show different features; At higher energy bands several peaks are seen in the light curve, while at lower energy band a single broader bump is dominated. It is expected that these different features are the result of mixture of several components each of which has different energetics and variability. To reveal the nature of each component, we analysed the time resolved spectra and they are successfully resolved into several components.
