Title: Golf club head

Abstract: A golf club head 10 includes a crown portion 11, a face portion 12, a side portion 13 a back face portion 14, and a neck portion 15. The crown portion 11 has a protruded portion in which a maximum point P of a curved contour of a central cross section (X--X line) of the crown portion is positioned rearwardly of the center I of the golf club head, and a cut-away portion obtained by obliquely cutting off the rear peripheral portion thereof. A volume V2 of a back-face-portion-side portion of the golf club head, which is positioned rearwardly of the head center I, is greater than a volume V2 of a face-portion-side portion of the golf club head, which is positioned in front of the head center I. On the curved contour of a central cross section of the crown portion 11, a relationship AB<CD is established where AB denotes a height between a leading edge of the golf club head front portion and the top edge A of the face portion, and CD denotes a height between an upper edge C of the cutaway portion and the intersecting point D at which the perpendicular drawn from the upper edge C intersects the back face portion.
