An electronic device has a first device holder and a second device holder each having a heat generating device attached thereto, a first heat conductive plate and a second heat conductive plate which are connected to the first and second device holders, respectively, a first heat dissipating fin disposed by the side of the second device holder which is disposed adjacent to the first device holder, a second heat dissipating fin disposed adjacent to the first heat dissipating fin in the same direction as the first heat dissipating fin, two first heat pipes which connect the first device holder with the first heat dissipating fin so that heat can be conducted therebetween, and a second heat pipe which connects the second device holder and the second heat dissipating fin so that heat can be conducted therebetween and which is disposed between the two first heat pipes.
