Abstract: The present disclosure relates to a cable bead for a pneumatic tire which constitutes a bead part of a pneumatic tire, improves rubber permeability by restricting a ratio between a diameter of a cable and a pitch of an outer wire, and improves durability of a pneumatic tire by improving rubber adhesive properties through cobalt coating on a surface of the outer wire, and a pneumatic tire having the same, and the cable bead for a pneumatic tire is characterized in that the diameter D of the cable and a pitch P of the outer wire 20 satisfy a relationship formula, P/D=25 to 45, and further characterized in that the surface of the outer wire 20 is coated with cobalt after wire drawing.
