In a golf club head, a horizontal direction oriented from the toe side toward the heel side is defined as an X direction, while a vertical upward direction is defined as a Y direction; and the coordinate of the center of the hit face is defined as (0, 0); the coordinate of the sweet spot is defined as (x1, y1); and the coordinate of the maximum resilience point on the hit face is defined as (x2, y2). In this golf club head, x1 is +3 mm or greater and +8 mm or less, and x2 is −5 mm or greater and +2 mm or less. Preferably, the shortest distance D1 between the axis line of the shaft hole and the center of gravity G of the head is 33 mm or greater and 44 mm or less. Preferably, when the face member is divided into a toe portion and a heel portion by a plane that passes the center of the hit face along the Y direction, the area mean thickness Tt of the toe portion is smaller than the area mean thickness Th of the heel portion.
