PROBLEM TO BE SOLVED: To provide a fatigue detector which detects fatigue with accuracy by easy processing by continuing to walk and run with a plurality of acceleration sensors attached on appropriate places of a body. SOLUTION: The fatigue detector stores acceleration signals detected by a first acceleration sensor 1a attached on hips and a second acceleration sensor 1b attached on a leg in a data storage part 3 sequentially in time. A data processing part 2 reads out the stored acceleration signals from the data storage part 3 to calculate a temporal difference between the acceleration signal of the first acceleration sensor 1a and the acceleration signal of the second acceleration sensor 1b which is delayed from the acceleration signal of the first acceleration sensor, compares the calculated temporal difference to a reference temporal difference, and outputs a warning of fatigue when the calculated temporal difference is greater than the reference temporal difference.
