Fully developed turbulent reacting jet formed by introducing inlet condition given by a turbulent channel flow was analyzed by the data base fo direct numerical simulation. We show that characteristic vortex structure exist in fully developed turbulent jet. Spanwize vortices exist in high-shear region and streamwise vortices bridge gaps between spanwize vortices. Detailed interpretation has been made to elucidate the interactions between vortex distribution, where streamwise and spanwize vorticities interact. Streamwise vorticity becomes large where spanwize vorticity is large, which indicate that rotation of spanwize vortices stretch streamwise ones.
