1. A terminal module for a rotating electric machine mounted on an end surface in an axial direction of a stator of the rotating electric machine, comprising:
- a ring-shaped bus bar housing having a groove extending in a circumferential direction; and
a bus bar fitted into said groove,said bus bar housing having a guide portion for determining a phase of rotation of the bus bar housing about said axial direction,said bus bar including a plurality of members arranged in a radial direction of said bus bar housing,said guide portion being provided at a position where all of said plurality of members arranged in the radial direction of said bus bar housing are divided in the circumferential direction of said bus bar housing,wherein a space is formed in said bus bar housing in which all of said plurality of members are not formed, and said guide portion is provided only at a position in the space of the bus bar housing where all of said plurality of members are not formed.

4. A method of manufacturing a rotating electric machine, comprising the steps of:
-
holding a ring-shaped terminal module for the rotating electric machine by a holder while determining a phase of rotation of said terminal module about an axial direction by inserting a guide pin into a guide portion formed in said terminal module; and mounting said terminal module held by said holder to a stator core, wherein said guide portion is only formed in a portion of said terminal module in which bus bars are not formed.
