To provide a power generation type wheel which is provided with a power generation function within the wheel holding a tire so that electric power generated during traveling of the vehicle is used as a travel energy or used to supply power.

The rotation of an axle 1 rotates a wheel 33, a cover protector 9, and a resin mold part 13. Consequently, a permanent magnet 11 is rotated as well. The permanent magnet 11 has a magnetic flux generated radially. Since the leg 17b of an external cross conductor 17 and the leg 31b of an inner cross conductor 31 which face the permanent magnet 11 are at a standstill, the rotating magnetic flux cross the leg 17b of the external cross conductor 17 and the leg 31b of the inner cross conductor 31. Power is obtained from lead wires 29a and 29b on the basis of induction voltage generated at the leg 17b of the external cross conductor 17 and the leg 31b of the inner cross conductor 31.
