In a golf club head having a shape of a Mallet-type patter, a width of a sole face is in a range of 30 mm to 80 mm. A loft angle of the golf club head is in a range of 10° to 40°. A thickness A of a top blade satisfies a relationship: 10 mm≦A≦SW−5 mm. A weight of the golf club head is in a range of 350 g to 450 g.

1 . A golf club head having a shape of a Mallet-type patter, wherein: 
 a width of a sole face is in a range of 30 mm to 80 mm,    a loft angle of the golf club head is in a range of 10° to 40°,    a thickness A of a top blade satisfies a relationship:     10 mm≦ A≦SW− 5 mm,   and    a weight of the golf club head is in a range of 350 g to 450 g.    
   
   
       2 . The golf club head according to  claim 1 , wherein: 
 the sole face extends approximately horizontally, and    a surface of the top blade is approximately parallel to the sole face.    
   
   
       3 . The golf club head according to  claim 1 , wherein a curvature radius of a contour of the sole face from a toe-side end to a heel-side end is greater than 300 mm.  
   
   
       4 . The golf club head according  claim 1 , wherein a height of the sole face at a position, which is distant from a heel by 10% of a length of the golf club head is in a range of 0 mm to 5 mm.  
   
   
       5 . The golf club head according to  claim 1 , comprising: 
 a hitting face having the loft angle of 10° to 40°;    a back face, which is opposite to the hitting face, being substantially perpendicular to a horizontal surface and substantially parallel to a shaft axis;    a plate portion that extends rearward from a lower end of the back face, the plate portion having a substantially semi-circular shape, the plate portion forming a part of the sole face; and    thick portions disposed on the plate portion on a heel side and a toe side.    
   
   
       6 . A golf club comprising: 
 a golf club head of  claim 1;     a shaft that is inserted into the golf club head directly or through a hozel; and    a neck portion formed with the top blade, the neck portion having a neck length equal to or less than 5 mm, wherein:    an overall length of the golf club is in a range of 33 inches to 36 inches.    
   
   
       7 . The golf club according to  claim 6 , wherein an interval between an axis of the shaft and a heel of a hitting face is equal to or less than 0.625 inch.
