Metal wood club head

The present invention relates to a metal wood golf club head, and more particularly, it relates to a metal wood club head bringing a wood club head of extra-large volume into a compact appearance shape, providing no feeling of misfit also when used by an upper-class person and capable of increasing a carry by remarkably improving restitution characteristics of the metal wood club head. A metal wood club head of a hollow hull structure according to the present invention is such that the vertical difference between a maximum face part height (MFH) from a sole part () and a back part height (BH) from the sole part () is at least within 25 mm, the height of a crown part () having a width of 30% to 70% of a head width from the sole part () is substantially identical to the maximum face part height (MFH) or more than that, the vertical difference between a maximum crown part height (MCH) from the sole part () and the maximum face part height (MFH) is at least within 8 mm, and the radius (R) of curvature of the crown part () is substantially uniformly within the range of 100 mm to 1000 mm, while it sets the radius (R) of curvature of the sole part () substantially uniformly within the range of 500 mm to 2000 mm, and sets the ratio of thicknesses of the crown part () and the sole part () within the range of 1.0 to 1.2.
