A precise measurement has been made utilizing a stacked CR-39 detectors for laser accelerated protons. The protons are accelerated from a thin polyimide target irradiated by intense Ti:sapphire laser (8 J energy and 40 fs duration). By analyzing the etch pits on the last layer of CR-39, the maximum proton energy is evaluated more precisely than in the past. The residual ranges for each particle in the last layer has been obtained from etch pit growth curves with the multi-step etching technique. The maximum energy of proton obtained is 14.39$$pm$$0.05 MeV. This method allows us to measure the maximum energy of proton precisely, which is ten times higher than that of the conventional methods.
