A Kummer-faithful field k is a perfect field such that the Kummer map associated to G is injective for every finite extension K of k and every semi-abelian variety G over K . A typical example of a Kummer-faithful field of characteristic zero is a sub- p -adic field for some prime number p . In particular, every number field is Kummer-faithful. In this paper, we give a construction of a Kummer-faithful field which is an infinite algebraic extension of the field of rational numbers. Moreover, we give some examples of Kummer-faithful fields which are not sub- p -adic by using the constructions.
