An upper plate constructed on a corner part of a sink is provided to improve workability due to easiness and convenience of work by being directly mounted on the corner part without a separate cutting work in the scene of labor. The upper plate constructed on a corner part of a sink includes: an outside corner wall(1) that an outside face of the upper plate and an outside wall formed on one side face meet perpendicular to each other; an inside corner wall(2) formed to be counter to the outside corner wall; and side faces(3) formed on both side ends of the outside corner wall and inside corner wall so as to connect to one side end of a straight-type upper plate.
