An iron type golf club head includes a head main body, a toe-side weight member made of a metal material having specific gravity ρ2 larger than that of the head main body and disposed on a toe-side of the head main body, and a heel-side weight member made of a metal material having specific gravity ρ3 larger than that of the head main body and disposed on a heel-side of the head main body. The head main body includes a face main portion having a face to hit a golf ball, and a tubular hosel portion provided continuously on a heel-side of the face main portion and having a shaft inserting hole.
