    Abstract: It is ensured the strength of a welded section in a tire that is configured by welding tire constituent members formed of a thermoplastic material. A tire has a first welded portion, in which one section of one tire constituent member and one section of another tire constituent member are both melted and welded, and a second welded portion, which is formed by welding a welding-use thermoplastic material to the surface of the first welded portion, whereby the strength of the joint section is ensured.
