1. A golf club head comprising:
- a face portion having a front face defining a club face for hitting a ball and a back surface;
a sole portion extending backwards from a lower edge of the face portion; and
a backside wall extending upwards from the sole portion and having a free upper end, said backside wall comprising an inclined portion inclined frontward so that a distance of a front surface of the inclined portion from said back surface of the face portion gradually decreases from a lower edge to an upper edge of the front surface of the inclined portion,wherein said inclined portion has a thickness gradually decreasing from the lower edge to the upper edge of the front surface of the inclined portion so that the minimum thickness (t3) is at least 0.5 times the maximum thickness (t2).

3. A golf club head comprising:
-
a face portion having a front face defining a club face for hitting a ball and a back surface; a sole portion extending backwards from a lower edge of the face portion; and a backside wall extending upwards from the sole portion and having a free upper end, said backside wall comprising an inclined portion inclined frontward so that a distance of a front surface of the inclined portion from said back surface of the face portion gradually decreases from a lower edge to an upper edge of the front surface of the inclined portion, wherein when said the distance between the front surface of the inclined portion from said back surface of the face portion is measured perpendicularly to the club face, the ratio (L2/L1) of a minimum value (L2) to a maximum value (L1) of the distance is in a range of from 0.1 to 0.7. - View Dependent Claims (4, 5, 6)
