PROBLEM TO BE SOLVED: To provide a bead core which can dispel the fear of deterioration of the fracture strength of the bead core due to the stress concentration at the cutting-off terminals of bead element wires, and can effectively prevent the rubbing of ply cords against the cut-off terminals of the bead element wires. SOLUTION: In the bead core 3 which is formed by winding the bead element wires 1 so as to form an annular shape and is arranged and buried in a bead portion of a tire, a pair of cut-off terminals 2 of the bead element wires 1 are placed on the wound portion defining the outside diameter of the bead core 3 respectively.
