PROBLEM TO BE SOLVED: To provide a golf swing analysis device capable of effectively providing a relative angle between an arm and a golf club to a user.SOLUTION: A first inertial sensor 12 is mounted to a portion of an upper half body of a golfer, and a second inertial sensor 13 is mounted to a golf club. A calculation unit calculates a relative angle &thetas; between the first inertial sensor 12 and the second inertial sensor 13 on the basis of outputs from the first inertial sensor 12 and the second inertial sensor 13. |
