PROBLEM TO BE SOLVED: To provide a bending and forming method capable of two-dimentional and three-dimentional bending and forming works with a single bending tool which does not require so much time for preparation and so much cost. SOLUTION: A wire fed by feed-control from a quill is pressure-welded along the outer periphery of the core die by independent operation of the first operation or the second operation or the combination operation to bend the wire to have the outer periphery of the core die, using a device equipped with a tool provided radially with respect to the revolving axis of the tool, in a tool holder capable of at least two operations of a first operation retractably moving in the axial direction of the quill guiding the wire Wa fed by feed-control and a second operation rotating around an axis orthogonal to the axis of the quill as the revolving axis of the tool, and a core die retractable toward the front face and the center of the quill 10 having the outer periphery on which a bending sectional shape of the wire Wa is formed.
