1. A disconnect device comprising:
a conductor connectable to an external conductive path;
a housing including an internal space, the internal space accommodating at least a part of the conductor;
a gas generator configured to generate gas by combustion of fuel;
an operation pin that is accommodated in the internal space, is disposed above the conductor, and is configured to move downward under a pressure of the gas generated in the gas generator, wherein
the conductor includes a terminal portion and a separation portion,
the terminal portion is held by the housing and is connected to the external conductive path, and
the separation portion is accommodated in the internal space of the housing and becomes separated from the terminal portion, as the pin moves downward; and

a cooling body that is disposed in the internal space, wherein
the cooling body includes a porous body configured with at least one of a metal oxide and an inorganic oxide,
the porous body has a fibrous structure and is deformable,
as the operation pin moves downward, the cooling body is configured to be compressed in a direction of movement of the operation pin, and
the cooling body is disposed below the separation portion before the separation portion is separated from the terminal portion.
