これによって、ヘッド全体重量が重くなる。However, in such a golf iron club having a conventional structure, the hitting portion b and the hosel portion c of the head body a are integrally formed of the same material. For example, when the head molding material is iron-based, the hosel portion c has a heavy weight of about 40 g,
As a result, the weight of the entire head becomes heavy.
