ELECTRICAL STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain an electrical storage device capable of precisely detecting a temperature of a capacitor held by a holding member using a temperature sensor.

SOLUTION: An electrical storage device 1 comprises a holding member 111 holding a capacitor 101 and a temperature detection sensor 45 for detecting a temperature of the capacitor 101 held by the holding member 111. The holding member 111 has a facing surface portion 141 facing an outer cover surface of the capacitor 101 held by the holding member 111 and a through-hole 141a formed through the facing surface portion 141. The temperature detection sensor 45 has a lid unit 45b sealing the through-hole 141a by being mounted to the holding member 111 and a sensor unit 45a supported by the lid unit 45b in such a way to be elastically deformable. The sensor unit 45a is elastically deformed by sealing the through-hole 141a using the lid unit 45b. The reaction force of the elastic deformation allows the sensor unit 45a to bring into contact with and press against the outer cover surface of the capacitor 101.
