A method for manufacturing an armature that includes an iron core and a coil , the iron core including slots , the coil being coupled to the slots of the iron core , the method comprising: a pressing step that presses a conductor of the coil in each of the slots and plastically deforms the conductor ; and a bending step that bends and deforms a protrusion in the conductor , the protrusion being located outside of the slot , wherein the pressing step includes pressing the conductor and extending the conductor in an axial direction of the iron core so that a small cross-sectional portion is formed in the protrusion , the small cross-sectional portion having a smaller cross-sectional area than a portion of the conductor that is not pressed, the bending step includes bending and deforming the small cross-sectional portion so as to bend and deform the protrusion , wherein the bending step includes bending and deforming the small cross-sectional portion while extending the conductor in the pressing step, and the conductor includes conductors the pressing step includes: a first step that presses a maximum number of the conductors capable of being arranged in each of the slots in a state in which the maximum number of the conductors are arranged in the slot , thereby extending the conductors ; and characterized in that a second step that presses a maximum number of the conductors capable of being arranged in a gap in the slot created by pressing the conductors in the first step in a state in which the maximum number of the conductors are arranged in the gap, thereby extending the conductors arranged in the gap. a pressing step that presses a conductor of the coil in each of the slots and plastically deforms the conductor ; and a bending step that bends and deforms a protrusion in the conductor , the protrusion being located outside of the slot , wherein the pressing step includes pressing the conductor and extending the conductor in an axial direction of the iron core so that a small cross-sectional portion is formed in the protrusion , the small cross-sectional portion having a smaller cross-sectional area than a portion of the conductor that is not pressed, the bending step includes bending and deforming the small cross-sectional portion so as to bend and deform the protrusion , wherein the bending step includes bending and deforming the small cross-sectional portion while extending the conductor in the pressing step, and the conductor includes conductors the pressing step includes: a first step that presses a maximum number of the conductors capable of being arranged in each of the slots in a state in which the maximum number of the conductors are arranged in the slot , thereby extending the conductors ; and characterized in that a second step that presses a maximum number of the conductors capable of being arranged in a gap in the slot created by pressing the conductors in the first step in a state in which the maximum number of the conductors are arranged in the gap, thereby extending the conductors arranged in the gap. a first step that presses a maximum number of the conductors capable of being arranged in each of the slots in a state in which the maximum number of the conductors are arranged in the slot , thereby extending the conductors ; and characterized in that a second step that presses a maximum number of the conductors capable of being arranged in a gap in the slot created by pressing the conductors in the first step in a state in which the maximum number of the conductors are arranged in the gap, thereby extending the conductors arranged in the gap. <EOS>
