Abstract: A disconnect device includes a cooling device having first and second main surfaces opposite to each other, a first insulator contacting the first main surface, a second insulator contacting the second main surface, a charging relay and a first discharging relay which contact a surface of the first insulator opposite to a surface of the first insulator contacting the first insulator, a protector contacting a surface of the second insulator opposite to a surface of the second insulator contacting the second main surface, a first power storage terminal configured to be connected to a first electrode of the power storage element, a second power storage terminal configured to be connected to a second electrode of the power storage element. The charging relay is separated from the discharging relay via a space between the charging relay and the discharging relay. At least a part of the protector faces the space across the first insulator, the cooling device, and the second insulator.
