Shock structure associated with magnetic reconnection is studied using three-dimensional magneto-hydro-dynamics simulations on the basis of the spontaneous fast reconnection model. In the two-dimensional reconnection, the angle between the slow shock pair (thickness of the plasma sheet) is smaller (thinner) in the region with higher reconnection rate. On the other hand, in the three-dimensional reconnection, the reconnection rate in the diffusion region is not uniform in the direction of sheet current, and the angle between the shock pair at the center of the diffusion region should be smallest. However, the profile of the angle in the direction of sheet current is not satisfied with this relationship. It is shown that this structure is caused by the inflow from the direction of the positive and negative sheet current and the inflow of the magnetic flux accompanied with it.
