PROBLEM TO BE SOLVED: To provide a new calculation method capable of calculating a locus having a small error from an actual movement locus, even if a gyro and a speed (acceleration) sensor having each comparatively low price respectively are used. SOLUTION: The device for calculating a movement locus of a moving object from the first spot P to the second spot Q after movement includes a storage device 21 for detecting the moving direction and the moving speed during movement from the first spot P to the second spot Q, and storing the results as movement data; a forward direction locus calculation part 31 for calculating a forward direction movement locus from the first spot to the second spot by using the stored movement data in the forward direction; a reverse direction locus calculation part 32 for calculating a reverse direction movement locus from the second spot to the first spot by using the stored movement data in the reverse direction; and a synthesis processing part 33 for synthesizing the forward direction movement locus and the reverse direction movement locus with a weighting ratio changing corresponding to a position to the first spot and the second spot.
