Abstract

The present invention provides a non-pneumatic tire, a tire and wheel assembly, a method for manufacturing a non-pneumatic tire, and a method for manufacturing a tire and wheel assembly that can reduce electrical resistance. [Solution] A non-pneumatic tire 1 comprises a resin case body 16, a tread member 14 disposed on the outer circumference side of the case body 16, an adhesive layer 5 that adheres the case body 16 and the tread member 14 together and is conductive, and a conductive path member 4 which is conductive. The case body 16 has an inner cylinder portion 11, an outer cylinder portion 12 disposed on the outer circumference side of the inner cylinder portion 11, and a connecting portion 13 that connects the inner cylinder portion 11 and the outer cylinder portion 12 to each other. The conductive path member 4 extends on the surface of the case body 16 and has a first portion 4b that is in contact with the adhesive layer 5.
