To provide a bead member including a resin bead filler of which a shape can be easily changed in manufacture of a tire and use of the tire, a pneumatic tire and an assembly.SOLUTION: A bead member 2 includes an annular bead filler 8 formed of a resin, where the bead filler 8 has an easy deformation part 9 which facilitates deformation in an axial direction provided at a part in the radial direction. The bead filler 8 is formed integrally with a core-coated resin Y coated with an annular bead core 7, and the easy deformation part 9 of the bead filler 8 is a constriction part 9a of which a width in a width direction is locally narrowed.SELECTED DRAWING: Figure 2
