Recent numerical simulations suggest that Population III (Pop III) stars wereborn with masses not larger than $\sim 100 M_{\odot}$ but typically $\sim40M_{\odot}$. By self-consistently considering the jet generation andpropagation in the envelope of these low mass Pop III stars, we find that a PopIII blue super giant star has the possibility to raise a gamma-ray burst (GRB)even though it keeps a massive hydrogen envelope. We evaluate observationalcharacters of Pop III GRBs and predict that Pop III GRBs have the duration of$\sim 10^5$ sec in the observer frame and the peak luminosity of $\sim 5 \times10^{50} {\rm erg} {\rm sec}^{-1}$. Assuming that the $E_p-L_p$ (or$E_p-E_{\gamma, \rm iso}$) correlation holds for Pop III GRBs, we find that thespectrum peak energy falls $\sim$ a few keV (or $\sim 100$ keV) in the observerframe. We discuss the detectability of Pop III GRBs by future satellitemissions such as EXIST and Lobster. If the $E_p-E_{\gamma, \rm iso}$correlation holds, we have the possibility to detect Pop III GRBs at $z \sim 9$as long duration X-ray rich GRBs by EXIST. On the other hand, if the $E_p-L_p$correlation holds, we have the possibility to detect Pop III GRBs up to $z \sim19$ as long duration X-ray flashes by Lobster.
