1. A golf club head comprising:
a face portion that forms a striking face;
a crown portion that forms a crown outer surface;
a sole portion that forms a sole outer surface; and
a hosel portion that is configured to receive a shaft and that defines a shaft axis line,
wherein the crown portion includes a protruding portion on the crown outer surface,
in a front view of the golf club head as viewed from a face side, the protruding portion does not form any part of an outer contour line of the golf club head,
wherein in a heel projection figure in which the golf club head that is placed on a ground plane such that the shaft axis line is perpendicular to the ground plane and a face angle is set at 0° is viewed from a heel side along the ground plane, the protruding portion forms a part of an outer contour line of the golf club head,
wherein the protruding portion includes an upper surface and a sidewall surface that extends from the upper surface to an outer edge of the protruding portion,
wherein the protruding portion has a contour line that includes a contour proximate side that is a side closest to the outer contour line in a planar view of the golf club head,
wherein the sidewall surface includes a contour proximate wall surface that has the contour proximate side as a lower edge of the contour proximate wall surface, and
wherein in the planar view of the golf club head, when an area of the protruding portion is denoted by St, and, of the crown outer surface, an area of a portion located on the heel side with respect to a face center is denoted by Sh, then a ratio of the area St to the area Sh is greater than or equal to 5% and less than or equal to 70%.
