Abstract (en)
[origin: EP1108448A1] A golf club head (1, 101) has a momental ellipsoid (10, 110). Assuming that three principal axes of the momental ellipsoid (10, 110) orthogonal to each other at the origin are an axis I1, an axis I2 and an axis Is in order of larger moments of inertia about the principal axes, the ratio (A/B) of a sectional area A at the time of cutting the momental ellipsoid (10, 110) along a plane passing through the origin and parallel to a face plane (11, 111) and a sectional area B at the time of cutting the momental ellipsoid along a plane including the axis I1 and the axis I2 is at least 1 and not more than 1.4. <IMAGE>
