As described above, according to the present invention, the same first iron club head with a wide variety of shapes can be obtained by combining a face member with the same shape and a back member with a different shape. It is no longer necessary to make a specific mold for each head with a different shape, and by changing the shape of only the back member to suit the purpose and combining it with the face member, the center of gravity of the head can be set arbitrarily. Therefore, it is also possible to expand the sweet spot area. In this way, when manufacturing iron club heads of a wide variety of shapes, only the back member needs to be newly developed, making it possible to significantly reduce development and manufacturing costs.
