This is a joint work with M. Sakaguchi and Y.Yasui. We construct an infinite family of inhomogeneous Einstein metrics on a 3-sphere bundle on a 2-sphere. They appear as limits of Kerr-de Sitter balck holes. Our construction is a higher dimesional version of the method of D. Page, by which he constructed an inhomogeneous compact Einstein 4-manifold.
