An electronic device includes a cabinet, a first heat generating member, a
second heat generating member, a fan unit, a first heat pipe and a second
heat pipe. The first and second heat pipes are each formed by sealing an
operation fluid which shifts its phase between gas and liquid into a
pipe-like main body. In the second position, the first end portion of the
first heat pipe is located at a position lower than that of the second
end portion and the one end portion of the second heat pipe is located at
a position higher than that of the other end portion. The second heat
pipe includes a conveying mechanism that conveys the operation fluid in
liquid phase from the other end portion to the one end portion.
