PROBLEM TO BE SOLVED: To provide a putt practice machine, discriminating the moving speed from the moving direction of a ball, sensing the precise moving speed and moving direction of the ball with minimum pieces of sensor equipment, holding down the production cost, hardly causing trouble, and facilitating handling. SOLUTION: This putt practice machine includes: a substantially oblong putting mat formed to be elongated toward the traveling direction of the ball to be putted; a first sensor provided on one long side of the putting mat, sensing passing of the putted ball and measuring the passing position of the putted ball; a second sensor provided on the other long side opposite to the above one side of the putting mat, sensing passing of the putted ball, and measuring the passing position of the putted ball; an operation means for operating the moving speed, the moving distance and the moving direction of the ball based on the passing position of the ball sensed and measured by the first sensor and the second sensor; and a display part for displaying the operation data operated by the operation means.
