PROBLEM TO BE SOLVED: To provide an accelerator pedal erroneous operation determining device capable of determining an erroneous operation of an accelerator pedal regardless of an individual difference of a driver. SOLUTION: An accelerator pedal erroneous operation determination device 10 can rotate to a portion where a foot LG of a driver DP who operates an accelerator pedal 12 comes into contact with an accelerator pedal 12 arranged on the vehicle front side and the vehicle lower side of a vehicle interior 14. Based on the rotation direction and angular velocity of the roller unit 30 which is provided in the above and has a detection unit 34 for detecting the rotation direction and the angular velocity, and the roller unit 30 which is electrically connected to the detection unit 34 and is detected by the detection unit 34. It includes an ECU 40 for determining whether or not the accelerator pedal is erroneously operated. [Selection diagram] Fig. 3
