A vortex row model which is composed of three layers of vortices periodically arranged in the flow direction is proposed in order to calculate the velocity profile of a turbulent boundary layer. In spite of its simplicity, the model is found to be very effective to describe the velocity profile as the function of Reynolds number. The result also gives important information of the structure of the turbulent boundary layer.
