PROBLEM TO BE SOLVED: To provide a golf club head and golf club capable of improving a carry.SOLUTION: A first groove part 5U extending from the side of a heel part 1h to the side of a toe part 1t along the outer shape of a top edge part 5 is formed in the top edge part 5. A second groove part 6U extending in a direction from the heel part 1h to the toe part 1t along the outer shape of a sole part 6 is formed in the sole part 6. The first ratio of a length L1 of a bottom of the first groove part 5U in a direction from the side of the heel part 1h to the toe part 1t to a head length L5 being the length of a whole golf club head 1 in a direction from the heel part 1h to the toe part 1t is equal to or more than 0.48 and equal to or lower than 0.63. The second ratio of a length of the second groove part 6U extending in a direction from the heel part 1h to the toe part 1t to the head length L5 is equal to or more than 0.48 and equal to or lower than 0.63. The third ratio of a height L3 of a face back surface 2B along a perpendicular bisector D of score lines 11 to a height L7 of a ball hitting surface 2A on the perpendicular bisector D is equal to or more than 0.97. |
