The 0.1-10 keV X-ray spectrum of a Seyfert galaxy known as Markarian 382 is presented based on observations with the EXOSAT. The energy index for the power-law X-ray continuum of Mkn 382 is measured to be 1.2 +0.16/-0.14, which is higher than the canonical value found for the Seyfert galaxies. There is no evidence for intrinsic absorption, soft excess or any line feature in the source. The X-ray emission was found to be steady during the observations. The 2-10 keV X-ray luminosity of Mkn 382 is 2.3 x 10 exp 43 erg/s.
