Multifunctional tire and production method therefor

A method for producing a multifunctional tire, comprising:

• preparing a device including a substrate and a flat secondary battery;
• preparing a tire configured to rotate about a rotation center;
• and
• fixing the device to the tire,
• wherein the flat secondary battery is connected to the substrate via a terminal, and the flat secondary battery is covered by a resin,
• the flat secondary battery includes an exterior body, and a positive electrode and a negative electrode disposed in the exterior body,
• the negative electrode contains a transition metal oxide as a negative electrode active material,
• the exterior body includes a positive electrode can having a bottomed cylindrical shape and a negative electrode can having a bottomed cylindrical shape,
• the negative electrode can faces the substrate, and
• the fixing of the device to the tire includes fixing the device to the tire to allow the flat secondary battery to be disposed outside the substrate as viewed from the rotation center of the tire
