Abstract
An iron golf club head comprises; a head main body including a club face provided with score lines; a weight member having a specific gravity larger than that of the head main body; and a fixing member having a specific gravity larger than that of the head main body and less than that of the weight member, and fixed to the head main body by welding so as to cover the weight member. In a forward tilting state of the club head in which the score lines are horizontal and the club face is vertical, the distance D in the perpendicular direction to the club face from the backmost position of the club head to the center of gravity of the weight member is not more than 47.3% of the maximum thickness w of the club head which is the shortest distance from the backmost position of the club head to the club face.
