Abstract
A method of manufacturing an armature coil includes the steps of: stacking multiple armature coils to generate a stack of armature coils in a stacking direction as a first step; securing first and second ends of the stack of armature coils with a pair of clamping dies, respectively, as a second step after completing the first step; and sandwiching and depressing the stack of armature coils with pressing die in a given direction intersecting the stacking direction as a third step after completing the second step. The pressing die includes a pair of sandwiching dies to sandwich and depress the stack of armature coils in the given direction. The pair of sandwiching dies has a narrower interval at a position closer to a first end of the stack than that at another position closer to a second end thereof.
