Provided is a bending device (10) having high productivity and capable of being installed in a reduced space, easily maintained, and manufacturing a bent member (35) consisting of a steel pipe (17) with high dimensional accuracy. The bending device (10) is provided with: a feeding mechanism (11) for feeding the steel pipe (17) in the longitudinal direction; a first support mechanism for supporting the steel pipe (17) while feeding the steel pipe; a heating mechanism (13) for heating a part of or the whole of the steel pipe (17) being fed; a cooling mechanism (14) for cooling the portion of the steel pipe (17) being fed, said portion being that which is heated by the heating mechanism (13); a second support mechanism (15) for bending the steel pipe (17) in a desired form by applying bending moment to the heated portion by moving the steel pipe (17) in the two-dimensional or three-dimensional direction while supporting at least a portion of the steel pipe (17) being fed; and a deformation prevention mechanism (16) for preventing the steel pipe (17) from being deformed. The feeding mechanism (11) is constituted of a first industrial robot (18) which is a seven-axis vertical multi-joint robot.
