AB: An X-ray jet is a phenomena discovered by SXT/Yohkoh and the observed properties of the X-ray jets are well explained by the X-ray jet model based on magnetic reconnection (Shibata et al. 1992). The model proposed that the X-ray jet is produced by the magnetic reconnection between pre-exist coronal magnetic field (a part of open field or large loops) and the emerging flux. The configuration is very simple and we can easily predict the position of the reconnection site. Hence, we think that an X-ray jet is a useful phenomenon for investigating the detail properties of reconnection process in the corona. In the study, we study the dynamics of fine structures and temperature structures of X-ray jets using X-ray images observed with the XRT/Hinode and investigate the detail properties of magnetic reconnection in corona. We also use the data of magnetic distribution taken by the SOT/Hinode and study the relationship of magnetic connectivity and reconnection process. At first, we found that two fine structure dynamics from the X-ray images observed with the XRT. One of the fine structures observed by XRT is an expanding loop. The loop appears near the footpoint of the jet when the footpoint brightening is observed. Additionally, we have found that the X-ray jets begin just after the expanding loop 'breaks'. Other fine structures discovered by XRT are thread-like features along the axis of the jets. XRT has shown that these thread structures compose the cross-section of jets. The fine structures and their motions strongly support the X-ray jet model based on magnetic reconnection, and also suggest that we must consider the three-dimensional configuration of magnetic field to understand jet phenomenon.�@In the paper, we also discuss the magnetic environment at X-ray jets sites and the temperature structure of X-ray jets.
