Abstract: The present paper presents a continuous selection theorem for closed bounded convex set-valued mapping which is defined on a conpact metric space and takes images in a n-Banach space (n>1). This mapping satisfies the assumption which is different from weak lower semi-continuity. The application is made to the fixed point theorem.

Key words: set-valued mapping, lower semi-continuous, continuous selection
