PROBLEM TO BE SOLVED: To provide a device determining a golf club suitable for a user by analyzing a swing.;SOLUTION: A golf swing analysis device 11 detects a state of a shaft 13a of a golf club 13 by using output of an inertial sensor 12, calculates a relative rotation angle varying by rotation around an axis of the shaft 13a during transition of the shaft 13a from a fist sate to a second state by swing motion of the shaft 13a, compares the relative rotation angle calculated and a reference relative rotation angle of a reference swing as a reference for at least one of a variation range of the relative rotation angle, time required for the relative rotation angle to be maximum from the first state, and a maximum value of the relative rotation angle, and outputs a comparison result.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
