  • the groove portion 13 b may extend continuously in the D 2 direction over an area of 60% to 90% (both inclusive) of the width H 1 .
  • each of the groove portions 13 a and 13 b is a straight groove, but it may be a curved groove.
  • the groove portion 13 b is formed on the heel side with respect to the central portion in the D 1 direction.
  • the groove portion 13 b may be formed in an area within a range of (1 ⁇ 3) ⁇ the width W from the heel side in the D 1 direction, or may be formed in an area within a range of (1 ⁇ 4) ⁇ W or (1 ⁇ 6) ⁇ W.

  • the groove portion 13 b may be distributed more on the lower side than on the upper side of the back surface 11 b.
  • the rib portion 14 a is formed on the upper side (top line 2 side) with respect to the central portion in the D 2 direction.
  • the rib portion 14 a may be formed in an area within a range of (1 ⁇ 3) ⁇ the width H 2 from the upper side in the direction D 2 , or may be formed in an area within a range of (1 ⁇ 4) ⁇ H 2 or (1 ⁇ 6) ⁇ H 2 .
  • the width of the extending area of the rib portion 14 a in the D 1 direction is L 21 , it is expressed by L 21 >(1 ⁇ 2) ⁇ W.
  • the length L 21 may be expressed by L 21 ⁇ (3 ⁇ 4) ⁇ W or L 21 ⁇ (4 ⁇ 5) ⁇ W.
  • the rib portion 14 a may be distributed more on the toe side than on the heel side of the back surface 11 b.
  • the rib portion 14 b is formed on the toe side with respect to the central portion in the D 1 direction.
  • the rib portion 14 b may be formed in an area within a range of (1 ⁇ 3) ⁇ the width W from the toe side in the D 1 direction, or may be formed in an area within a range of (1 ⁇ 4) ⁇ W or (1 ⁇ 6) ⁇ W.

  • the rib portion 14 b may be distributed more on the upper side than on the lower side of the back surface 11 b.
  • the toe-side end portion of the rib portion 14 a is connected to the upper end portion of the rib portion 14 b , so that the rib 14 has a vertically and horizontally inverted L-shape as a whole when viewed from the back surface of the wall portion 11 .
  • the midway portion of the rib portion 14 a may be connected to the upper end portion of the rib portion 14 b
  • the toe-side end portion of the rib portion 14 a may be connected to the midway portion of the rib portion 14 b
  • the rib portion 14 a may intersect the rib portion 14 b .
  • an iron type golf club head includes a hosel portion having a rigid structure on the heel side, and the sole width is thicker on the heel side than on the top side. Accordingly, the rigidity is high on the heel side, and low on the toe side and the top line side. Therefore, as shown as a position 15 ′ exemplified in FIG. 5 , the position of the antinode of the natural vibration tends to be located at a position on the toe side and the top line 2 side with respect to the central portion of the face portion 4 .
  • the striking point is deviated from the antinode position 15 ′, so that a carry of a shot may be decreased.
  • the iron type golf club head is often used to strike a ball placed on the ground. Accordingly, it has a high frequency of striking a ball at the lower portion of the face portion 4 .
  • the plurality of grooves 13 and the plurality of ribs 14 are provided, it is possible to make the position of the antinode of the natural vibration closer to the lower portion and central portion of the face portion 4 , as shown as a position 15 .
  • the groove 13 includes the groove portion 13 a , the rigidity of the face member 10 on the sole portion 3 side can be decreased. Accordingly, the antinode position 15 ′ can be moved to the sole portion 3 side.
  • the groove 13 includes the groove portion 13 b , the rigidity of the face member 10 on the heel side can be decreased. Accordingly, the antinode position 15 ′ can be moved to the heel side.
  • the rib 14 includes the rib portion 14 b , the rigidity of the face member 10 on the toe side can be increased. Accordingly, the antinode position 15 ′ can be further moved to the heel side. As a result, when a golf ball is struck at the central portion of the face portion 4 , the striking point is closer to the antinode position 15 , so that an increase in a carry of a shot can be achieved.
  • both the plurality of grooves 13 and the plurality of ribs 14 are used in the embodiment described above, but it is possible to move the position of the antinode of the natural vibration closer to the central portion of the face portion 4 by using either of the plurality of grooves 13 and the plurality or ribs 14 .
  • the groove 13 may include the groove portion 13 a alone, and even in this case, it is possible to move the position of the antinode of the natural vibration closer to the central portion of the face portion 4 in the D 2 direction.
  • the rib 14 may include the rib portion 14 a alone, and even in this case, it is possible to move the position of the antinode of the natural vibration closer to the central portion of the face portion 4 in the D 2 direction.
  • each of the plurality of grooves 13 includes the groove portion 13 a alone according to the embodiment described above.
  • each of the plurality of ribs 14 includes the rib portion 14 a alone according to the embodiment described above.
  • the groove 13 including the groove portion 13 b and the groove 13 including no groove portion 13 b may be mixed.
