Zusammenfassung:	The invention provides a tire with an electric power generation device for supplying sufficient electric power which has a simple and small-sized construction. An electric power generation device 100 for converting strain occurring in a tire 1 into electric energy includes at least one electric power generation element 10 and a device body 100a. The electric power generation element 10 has at least two stretchable electrodes 11 and a dielectric elastomer 12, arranged between the electrodes 11, and producing a potential difference between the electrodes 11 according to the strain applied from the tire 1. The device body 100a has an electrical condenser for accumulating electric energy produced by the electric power generation element 10. The length, in the circumferential direction of the tire, of the electric power generation element 10 is set so that strain by contraction and strain by expansion that are caused by the rotating tire 1 coming into contact with the ground surface are not simultaneously applied to the single power generation element 10.
