Electronic apparatus

An electronic apparatus comprising:

• a first member and a second member;
• and
• a device comprising:
• a reaction chamber containing a chemical heat storage material showing an endothermic reaction and an exothermic reaction reversibly;
• a condensation/evaporation chamber for condensing or evaporating a condensable component produced from the endothermic reaction of the chemical heat storage material;
• and a communication part communicating the reaction chamber with the condensation/evaporation chamber;
• wherein the first member is thermally combined with the reaction chamber, and the condensation/evaporation chamber is thermally combined with the second member.

An electronic apparatus having a function of suppressing a temperature rise of a heating generating element, comprising:

• a heat generating element;
• and
• at least one reaction chamber containing a chemical heat storage material,
• wherein heat generated from the heat generating element is transferred from an outer surface of the heat generating element to the chemical heat storage material in the at least one reaction chamber, and the chemical heat storage material absorbs the heat by a reaction to suppress the temperature rise of the heat generating element.
