An electron spectrometer (ESM) is designed and tested to measure high-energy electrons generated from ultra-intense laser plasma interactions. In this ESM, Fuji film imaging plate (IP) is often used as a detector for avoiding the influence by a strong electromagnetic noise. In previous study, IP was calibrated for electron up to 100-MeV in order to obtained absolute number of high-energetic electron. However, in more recent laser acceleration study 1-GeV monoenergetic electron beam was produced. Therefore, we performed the absolute calibration of IP for 1-GeV electrons experimentally at SPring-8. The 1-GeV electron beam was generated from Linac for injection to the storage ring at SPring-8. In the result, it has been proved that IP has sufficient sensitivity for 1-GeV electrons and the absolute sensitivity curve for electrons up to 1 GeV was obtained.
