Abstract (en)
An iron golf club head (1) has three principal axes (I1, I2, I3) of inertia passing through the center of gravity. An angle θ formed by such an axis (I1) that a moment of inertia about the principal axis of inertia is maximized among the three principal axes (I1, I2, I3) of inertia and a normal vector (101) of a face plane (3f) passing through the center of gravity is at least 10 degrees and not more than 90 degrees. <IMAGE>
