In this paper, we study an analogue of the Tate conjecture forof U, the complement of split multiplicative fibers in an elliptic surface. A main result is to give an upper bound of the rank of the Galois fixed part of the etale cohomology. As an application, we give an elliptic K3 surfaceover a p-adic field for which the torsion part of the Chow groupof 0-cycles is finite. This would be the first example of a surfaceover a p-adic field whose geometric genus is non-zero and for which the torsion part ofis finite.
