Abstract
An iron golf club head includes: a head portion; and a badge portion adhered to the head portion. The head portion includes: a face surface; and a back surface located behind the face surface. The badge portion is adhered to at least one of a first largest amplitude region where an amplitude in a fourth-order vibration mode of the back surface is the largest and a second largest amplitude region where an amplitude in a fifth-order vibration mode of the back surface is the largest. As a result, there can be obtained an iron golf club head and an iron golf club, in which by suppressing decrease in resonant time of the hitting sound and reducing the sound pressure of the hitting sound, the hitting sound and the hitting feeling can be improved.
