There is provided an electronic apparatus having a novel means capable of suppressing temperature rise of a heat generating element. The electronic apparatus (20), which includes a heat generating element, is provided with a device (or a chemical heat pump) (10) comprising: a reaction chamber (1) containing a chemical heat storage material showing an endothermic reaction in response to heat emitted by the heat generating element (11); a condensation/evaporation chamber (3) for condensing or evaporating a condensable component produced from the endothermic reaction of the chemical heat storage material; and a communication part (5) communicating the reaction chamber (1) with the condensation/evaporation chamber (3) such that the condensable component is movable between the reaction chamber (1) and the condensation/evaporation chamber (3).
