Patent abstract
A hollow golf club head has a face portion, a crown portion, and a sole portion. Assuming that a primary deflection mode frequency of the face portion is Ff, a primary deflection mode frequency of the crown portion is Fc, and a primary deflection mode frequency of the sole portion is Fs, the Ff, Fc and Fs satisfy the following expressions: 3000 Hz<Ff<4000 Hz; 3000 Hz<Fc<4000 Hz; Fs>4000 Hz. The face portion, the crown portion and the sole portion have no mode frequency of 3000 Hz or less.
