To solve such problems of the conventional large-sized iron heads as the high position of a sweet spot and the distance between a meet point and the sweet spot greater than that of the iron heads of the conventional sizes and the consequent decrease in a distance.

A head body 2 is formed by using a blank having a small specific gravity to a cavity back and low centroid and a weight member 3 having the large specific gravity is fitted into a recessed part 2b formed at a sole 21, by which the sweet spot SS is so set as to keep the height from the sole 21 within a specified range and is brought near to the meet point MP.
