In this research oriented manuscript, foundational aspects of rigid geometry are discussed, putting emphasis on birational side of formal schemes and topological feature of rigid spaces. Besides the rigid geometry itself, topics include the general theory of formal schemes and formal algebraic spaces, based on a theory of complete rings which are not necessarily Noetherian (cf. introduction). The manuscript is encyclopedic and almost self-contained, and contains plenty of new results. A discussion on relationship with J. Tate's rigid analytic geometry, V. Berkovich's analytic geometry and R. Huber's adic spaces is also included. As a model example of applications, a proof of Nagata's compactification theorem for schemes is given in the appendix.
