An iron-type golf club head has a face portion which comprises a central part, a face peripheral part surrounding the central part and protruding backward therefrom to form a cavity, and a badge disposed within the cavity. The central part comprises: a central thin region having a minimum thickness of the face portion and a rear surface to which the badge is attached; a thicker peripheral region surrounding the badge and having an inner circumferential surface raising from the rear surface of the central thin region to position the badge, the thicker peripheral region having at least one breaking part; and at least one radial thin region formed by the breaking part and extending from the central thin region to the face peripheral part.
