The change in structure and viscoelasticity of aqueous solutions of thread-like micelles of cetyltrimetylammonium bromide and sodium salicylate under steady shear flow were investigated by small angle neutron scattering and viscoelastic measurements. Two dimensional neutron scattering measurements showed that the same scattering profiles were observed for both vertical and horizontal directions at 1 sec -1 and above 200 sec -1. On the other hand, scattering intensity in the vertical direction was stronger than that in the horizontal direction at 10 ∼ 100 sec -1. In that shear rate region, shear stress was almost constant, while first normal stress difference was almost proportional to shear rate.
