The phtodisintegration reactions of 4He nuclei i.e., 4He(γ,pt) and 4He(γ,3He)n, play crucial roles for the nucleosynthesis in the universe, but the result of previous experimental studys show sizable discrepancies. We performed the measurement of these reactions with the TPC-based MAIKo active target. The MAIKo active target enable us to detect, the sensitivity for the low energy decay particles emitted to full solid angle. The mearsurement were carried out at the New SUBARU synchrotron radiation facility, and the qusi-monoquromatic pulsed photon beam were irradiated on MAIKo. The data analysis has been partially done. The number of true events were counted by tracking of recorded images, and the total flux of photon beams was determined by the analysis of the spectrum recorded by the NaI beam monitor.
