In the rotary electric machine, bus-bar lead terminals of bus bars, which are held by a connection component, are formed in such a way that the bus-bar lead terminals are protruded from the bus bars to an axis direction of a stator, and a plurality of bus-bar storage grooves are formed by using a plurality of partitions which are concentrically arranged in a diameter direction of the stator via gaps, and in the plurality of partitions, lengths, in the axis direction, of the most outer circumference partition, which is positioned at the most outer circumference side in the diameter direction, and the most inner circumference partition, which is positioned at the most inner circumference side in the diameter direction, are longer than lengths, in the axis direction, of a plurality of middle partitions, which are positioned between the most outer circumference partition and the most inner circumference partition.
