The abundance in M82 is Si and S rich, and can not be explained by the combination of conventional Type I and II supernova yields. We show that these abundance patterns, as well as the observed hot plasma energy to metal mass ratios can be explained by the hypernova nucleosynthesis. This hypothesis is consistent with the expected age after the star-burst of M82.
