To provide a bead filler that can be formed into a shape that is close to an intended design shape when a bead filler is formed by injection molding, and to provide a pneumatic tire.SOLUTION: A bead filler is formed of a thermoplastic resin. The bead filler has a thickness that gradually decreases toward the outside in a radial direction of the tire from a bead core as the bead filler extends, in other words, the bead filler has a thick bottom part. The bead filler includes multiple bubbles formed inside thereof.SELECTED DRAWING: Figure 4

    【課題】射出成形によってビードフィラーを成形する場合に、設計の狙い通りの形状に近づけることができるビードフィラー、及び空気入りタイヤを得る。【解決手段】ビードフィラーは、熱可塑性の樹脂で形成され、ビードコアからタイヤの径方向の外側に向けて厚さが徐々に減少するように延びている。つまり、ビードフィラーの根元の部分は、厚肉となっている。さらに、ビードフィラーの内部には、複数の気泡が形成されている。【選択図】図4
