A bus bar module includes: a plurality of linear conductors disposed in parallel at predetermined intervals; a belt-form flat conductor disposed adjacent to the linear conductors and extending in an axial direction of the linear conductors; and an insulating resin portion that integrally covers outer peripheral portions of the plurality of linear conductors and one side edge portion of the flat conductor, the one side edge portion being adjacent to the linear conductors. A tensile strength of the flat conductor and the insulating resin portion is not less than 50 N/mm2.
