A binding machine, comprising: a wire feeding portion which feeds a wire; a cutting portion which is provided on a downstream side of the wire feeding portion along a feeding direction of the wire fed by the wire feeding portion and cuts the wire; and a guide portion which is provided on a downstream side of the cutting portion along the feeding direction of the wire and causes the wire to curl by regulating an advancing direction of the wire, wherein the cutting portion includes: a fixed blade in which a first wire passage through which the wire passes is formed; a movable blade in which a second wire passage through which the wire passes is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire; a driving member which is connected to the movable blade and drives the movable blade; a driving portion which drives the driving member; and a control unit for which controls the driving portion, the movable blade is capable of moving between a standby position where the first wire passage and the second wire passage communicate with each other and a movement finish position where the first wire passage and the second wire passage do not communicate with each other by sliding on the outer peripheral surface of the fixed blade, characterized in that the control unit controls the driving portion such that the movable blade is moved by a predetermined amount in a direction of cutting the wire after the movable blade is moved from the movement finish position to the standby position, and then the movable blade is moved to the standby position. a wire feeding portion which feeds a wire; a cutting portion which is provided on a downstream side of the wire feeding portion along a feeding direction of the wire fed by the wire feeding portion and cuts the wire; and a guide portion which is provided on a downstream side of the cutting portion along the feeding direction of the wire and causes the wire to curl by regulating an advancing direction of the wire, wherein the cutting portion includes: a fixed blade in which a first wire passage through which the wire passes is formed; a movable blade in which a second wire passage through which the wire passes is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire; a driving member which is connected to the movable blade and drives the movable blade; a driving portion which drives the driving member; and a control unit for which controls the driving portion, a fixed blade in which a first wire passage through which the wire passes is formed; a movable blade in which a second wire passage through which the wire passes is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire; a driving member which is connected to the movable blade and drives the movable blade; a driving portion which drives the driving member; and a control unit for which controls the driving portion, the movable blade is capable of moving between a standby position where the first wire passage and the second wire passage communicate with each other and a movement finish position where the first wire passage and the second wire passage do not communicate with each other by sliding on the outer peripheral surface of the fixed blade, characterized in that the control unit controls the driving portion such that the movable blade is moved by a predetermined amount in a direction of cutting the wire after the movable blade is moved from the movement finish position to the standby position, and then the movable blade is moved to the standby position.
