PROBLEM TO BE SOLVED: To provide a binding method in which a work is bound by a binding band in a reliably tightened condition without any space between the work and the binding band. SOLUTION: A band portion 2 of the binding band 1 is bent in cooperation with first and second guide members 24 and 26, and the band portion 2 is passed through a hole 7 in a head portion 3 while the head portion 3 of the binding band 1 is temporarily regulated in position by a stopper 38 held by a tension spring 39. A projecting portion from the head portion in the band portion 2 is held by a gear 43 and a band portion holding surface 46 of a guide plate 45, and pulled. In pulling the band portion 2, the stopper 38 moves the band portion along a groove 37 against the tension of the tension spring 39, the head portion 3 of the binding band 1 is moved to tighten reinforcing bars A and B. The hole 7 in the head portion 3 of the binding band 1 is directed by this binding force to the center direction which is a piercing direction of the portions to be bound of the reinforcing bars A and B, a proximal portion of the hole 7 in the head 3 in the band portion 2 is disposed along an outer surface of the reinforcing bar A to reduce a spacing between the binding band 1 and the reinforcing bar A.
