A tube bender is provided to change one bend radius to another easily and to improve productivity by bending plural tubes at the same time. A tube bender capable of changing a bend radius easily and bending plural tubes at the same time includes a plate-shape base(10), a bending roll(30) which determines a bend radius of a tube(20) with inserting some portion of the tube to a groove provided on the roll and which is centered at one of holes provided on the table to center, a tube stopper(40) which is fixed at one of plural holes on the table to prevent the tube from being taken off from the table when bent by the bending roll, a scale(50) to measure the length of the tube, and a bending arm(60) for bending the tube wound on the bending roll trapped by a roller(61) of the bending arm located opposite to the bending roll.
