A bead core of the present disclosure is a bead core comprising an annular body in which a strip member comprising one or more bead wires coated with a coating resin is wound and stacked, and in an axial cross section of the annular body, an interface between stacks adjacent to each other is non-linear. A manufacturing method of a bead core of the present disclosure comprises an annular body forming step of winding and stacking a strip member comprising one or more bead wires coated with a coating resin to form an annular body, and the strip member has a side that comes in contact with an adjacent stack in the annular body forming step and that is non-linear in a cross section orthogonal to an extending direction of the strip member.
