    Abstract: A cooling device having a heat receiving portion, a heat radiating portion, a heat pipe, and a fan. The heat receiving portion is held on a wiring board and thermally connected to a heat-generating component. The heat radiating portion radiates the heat generated by the heat-generating component, at a position remote from the heat receiving portion. The heat pipe transfers the heat generated by the heat-generating component, from the heat receiving portion to the heat radiating portion. The heat pipe couples the heat receiving portion and the heat radiating portion. The fan applies cooling air to the heat radiating portion. The fan is coupled to the heat radiating portion.
