Thermistor attachment configuration for a bus bar module

A bus bar module comprising:

• a case attached to a battery assembly comprising a plurality of single cells;
• a bus bar supported by the case and electrically connected to electrodes of the plurality of single cells of the battery assembly;
• and
• a plurality of electric wires routed in the case,
• wherein the plurality of electric wires comprise:
• a plurality of voltage detection electric wires connected to a plurality of voltage detection terminals, respectively, the plurality of voltage detection terminals being connected to the bus bar, and
• a temperature measurement electric wire connected to a thermistor configured to measure a temperature of at least one of the plurality of single cells,
• wherein the case comprises:
• an electric wire routing groove portion in which the plurality of voltage detection electric wires are routed, and
• a thermistor attachment portion having a mounting hole to which the thermistor is attached,
• wherein the mounting hole is formed such that a longitudinal direction of the mounting hole is perpendicular to a routing direction of the plurality of voltage detection electric wires in the electric wire routing groove portion, and
• wherein the thermistor attachment portion is provided in the electric wire routing groove portion.
