To provide a pneumatic tire that can improve durability of a conductive part and maintain charging suppression performance.SOLUTION: A pneumatic tire 1 comprises: a pair of bead parts 10 and 10; at least one carcass layer 13 hung across the pair of bead parts 10 and 10; a belt layer 14 arranged outside in a tire radial direction of the carcass layer 13; a tread rubber 15 arranged outside in the tire radial direction of the belt layer 14; and a pair of side wall rubbers 16 and 16 arranged outside respectively in a tire width direction of the carcass layer 13, which further comprises a conductive part 52 extended continuously at least from the bead parts 10 to the belt layer 14 and arranged along a surface 13a of the carcass layer 13. The conductive part 52 is configured to include a conductive linear body 521 formed by molding a conductive substance having electric resistivity of 1×10^8[Ω/cm] or less into a linear shape, and has at least one separation part 53 which separates from the surface 13a of the carcass layer 13.SELECTED DRAWING: Figure 2

    【課題】導電部の耐久性を向上させることができ、帯電抑制性能を維持することのできる空気入りタイヤを提供すること。【解決手段】一対のビード部10、10と、一対のビード部10、10間に架け渡される少なくとも1層のカーカス層13と、カーカス層13のタイヤ径方向外側に配置されるベルト層14と、ベルト層14のタイヤ径方向外側に配置されるトレッドゴム15と、カーカス層13のタイヤ幅方向外側にそれぞれ配置される一対のサイドウォールゴム16、16とを備える空気入りタイヤ1であって、少なくともビード部10からベルト層14まで連続して延在し、カーカス層13の表面13aに沿って配置される導電部52を備え、導電部52は、1×10^8[Ω/cm]未満の電気抵抗率をもつ導電物質を線状に成形して成る導電線状体521を含んで構成され、且つ、カーカス層13の表面13aから離間する離間部53を少なくとも一箇所有する。【選択図】図2
