1. A stator of a rotary electric machine, the stator comprising:
a coil end of a stator coil, the coil end protruding axially from a plurality of slots of a stator core;
a connection unit which is arranged in an axial direction of the coil end and includes a connection conductor;
an insertion member which extends from the connection unit toward the coil end and is inserted into the coil end; and
a resin member comprising a bridge member which (i) is positioned between the coil end and the insertion member and (ii) couples the coil end and the insertion member,
wherein the coil end includes a plurality of segment conductors that each connect one straight member of the stator coil that is positioned in one of the plurality of slots to another straight member of the stator coil that is positioned in a different one of the plurality of slots, and
wherein the insertion member is inserted into a gap between the plurality of segment conductors forming the coil end.
