To provide a pneumatic tire capable of satisfactorily maintaining antistatic performance.SOLUTION: A pneumatic tire includes a tread part 1, a pair of side wall parts 2 and a pair of bead parts 3, and has a carcass layer 4 mounted between the bead parts 3 and 3, where a plurality of conductive filaments 20 containing conductive fibers having electric resistivity of less than 1×10Ω cm are arranged on the carcass layer 4 with an angle to a tire radial direction so as to extend between the pair of bead parts 3 and 3, and the conductive filaments 20 are brought into contact with each other so as to cross each other in at least one portion.SELECTED DRAWING: Figure 3
【課題】 帯電防止性能を良好に維持することを可能にした空気入りタイヤを提供する。【解決手段】 トレッド部1と一対のサイドウォール部2と一対のビード部3とを備え、ビード部3,3間にカーカス層4が装架された空気入りタイヤにおいて、電気抵抗率が1×108Ω・cm未満である導電性繊維を含む複数本の導電性線状体20が一対のビード部3,3間に延在するようにカーカス層4上でタイヤラジアル方向に対して角度を付けて配置され、導電性線状体20が少なくとも1箇所で互いに交差しながら接触する。【選択図】 図3
