To provide a structure of a head in an iron club for golf in which grass resistance at the time of shot can extensively be reduced, follow-through of swing of a club head can easily be conducted in the rough even by beginners and powerless golfers, poor shot (miss a shot) such as chip and shank can effectively be eliminated, and safety is ensured by solving the problem of accident resulting in injury and death by shank, etc. The structure of a head in an iron club for golf includes a grass relief groove 5 which is formed in a leading edge portion zone 4 of a club head 1 such that the grass relief groove 5 is open at a leading edge 4a and released at a surface 4b on the side of the striking face 2 of the leading edge portion zone 4 and at a surface 4c on the side of a sole face 3 of the leading edge portion zone 4.
