Abstract
This electronic apparatuscomprises a heating element, and a case. The casehas an opening hole. In order that a refrigerant COO will be sealed between the caseand the heating element, the outer periphery part of a first heating element external surface, which is the external surface of the heating element, is attached to the outer periphery part of the opening hole. Also, the refrigerant COO is a refrigerant that is capable of phase change from a liquid refrigerant LP-COO to a gas phase refrigerant GP-COO. As a result, it is possible to more efficiently cool the heat of the heating element
