1. A power storage device comprising:
a holding member holding power storage units; and at least one temperature detection sensor detecting temperature of the power storage units held by the holding member, wherein the holding member includes a facing surface portion facing coated surfaces of the power storage units held by the holding member, and at least one through hole formed so as to pierce through the facing surface portion, the temperature detection sensor includes a lid unit closing the through hole by being attached to the holding member, and a sensor unit supported in the lid unit so as to be elastically deformed, which is elastically deformed when the lid unit closes the through hole, pressed and contacted onto the coated surface of the power storage unit due to reaction force of elastic deformation, wherein the sensor unit includes a sensor housing having a temperature detection device, and elastic pieces extended from the sensor housing and supported in the lid unit, and wherein the holding member includes a groove for wire rods formed on the facing surface portion so as to connect to the through hole, in which sensor wire rods of the temperature detection device are wired, and the temperature detection sensor has a bushing into which the sensor wire rods of the temperature detection device are inserted, sealing between the through hole and the groove for wire rods. |
