Abstract
We present the string Lagrangian with manifest T-duality. Not only zero-modes but also all string modes are doubled. The gravitational field is an O(D, D) gauge field. We give a Lagrangian version of the section condition for the gauge invariance which compensates the O(D, D) transformation from the gravitational field and the GL(2D) coordinate transformation. We also show the gauge invariance of the line element of the manifest T-duality space and the O(D, D) condition on the background. Different sections describe dual spaces.
