Studies has been carried out on the characteristics of thermally stimulated current for polypropylene in the temperature range of $293[^{\circ}K]{\sim}403[^{\circ}K]$. The main peak observed at $366[^{\circ}K]$, as may be $\beta$ peak in conventional nomination, is believed to be depolarization current originated from the relaxation of "CO" group in monomer structure. The activation energy for the observed peak has been concluded to be in the range of $0.6{\sim}0.7[(eV]$ at $360[^{\circ}K]$ by the initial rise method. Furthermore, the initial density of carriers were calculated about $10^{22}/m^3$
