A club head of a golf driver having an increased surface area is provided to control the air flow velocity more effectively, thereby improving directional characteristics and control force of the golf driver. A club head(10) of a golf driver includes: at least one auxiliary wing(30) mounted on a rear portion(11) of the club head in parallel or vertically to be able to control an upward force and/or direction of air. To the end, the auxiliary wing is constituted of a parallel wing portion(31) and a vertical wing portion(32). Further, the auxiliary wing is detachably coupled or welded to the club head through fastening elements such as bolts and screws, or detachable elements. Particularly, the vertical wing portion functions as a tail wing of an air plane, thereby moving the club head inwardly or outwardly of the golfer during high-speed swing.
