The purpose of the present invention is to provide a cooling device offering excellent uniformity of cooling for a plurality of heating elements generating different amounts of heat. Provided is a cooling device having: a first heat pipe one end section of which is thermally connected with a first heating element, and another end section of which is thermally connected with a first heat-radiating fin group having a plurality of first heat-radiating fins and a second heat-radiating fin group having a plurality of second heat-radiating fins; and a second heat pipe one end of which is thermally connected with a second heating element provided closer to the second heat-radiating fin group than the first heating element, and another end of which is thermally connected with the second heat-radiating fin group and a third heat-radiating fin group having a plurality of third heat-radiating fins. The second heat-radiating fin group faces the first heat-radiating fin group with the first heat pipe interposed therebetween, and the second heat-radiating fin group faces the third heat-radiating fin group with the second heat pipe interposed therebetween. Due to the foregoing, the first heat-radiating fin group, the second heat-radiating fin group, and the third heat-radiating fin group form a laminated structure, with the other end section of the first heat pipe being located above the other end section of the second heat pipe. |
