Patent ID: 6976526

Claim:
An electronic device having a heat transport mechanism, wherein the heat transport mechanism comprises: an evaporator which has a structure for generating a capillary force to circulate working fluid, to which a heating section is thermally connected, and in which liquid-phase working fluid evaporates; a condenser in which vapor-phase working fluid condenses; a plurality of liquid channels through which the liquid-phase working fluid flows, and which connect the evaporator and the condenser; and at least one vapor channel through which the vapor-phase working fluid flows, wherein the plurality of liquid channels, the vapor channel, the evaporator, and the condenser are provided in a same substrate structure, an insulating section is provided along the plurality of liquid channels and the at least one vapor channel to suppress heat transmission between the plurality of liquid channels and the at least one vapor channel and an outside, or between the plurality of liquid channels and the at least one vapor channel, and the insulating section is a cavity defined by a through hole provided in a portion of the substrate structure, where the through hole is provided in a second substrate sandwiched between a first substrate and a third substrate portion of the substrate structure, the first substrate and the third substrate portion close the through hole.
