Abstract: A structure for attaching a temperature detection member to a bus bar includes: a bus bar that is overlaid on electrode terminals of single-cell batteries each having positive and negative electrode terminals and electrically connects adjacent electrode terminals of the plurality of single-cell batteries; and a temperature detection member configured to detect the temperature of the bus bar, wherein the temperature detection member includes a plate-shaped detection portion, the detection portion being overlaid on a region of the bus bar other than regions overlaid on the electrode terminals, and the detection portion has a crimped piece that is crimped to the bus bar.
