Claim One:
1. A method for golf club selection using a behavior of a golf swing when a golf club is gripped and swung, comprising the steps of: obtaining, during a golf swing, a first value of an approach angle of a golf club head in a vertical direction relative to a horizontal plane immediately before striking a golf ball, and a second value of an approach angle of the golf club head in a horizontal direction on a plane parallel to the horizontal plane immediately before striking the golf ball; classifying the golf swing as one of predetermined types using the obtained first value and the obtained second value; and selecting a golf club suited for the one of the predetermined types according to a classification result, wherein said classifying step is performed by plotting as a point showing a state of the golf swing the obtained first value and the obtained second value on a two-dimensional chart in which the approach angle in the horizontal direction and the approach angle in the vertical direction are two coordinate axes.
