To provide a compact cooling device using a refrigeration cycle, and a laptop computer.

An electronic apparatus 10 has a housing portion 30 in which a functional element 36 operating while generating heat is stored. The housing portion 30 houses the cooling device comprising: a compressing means 41 of compressing a refrigerant; a condensing means 42 of liquefying the refrigerant by emitting heat from the refrigerant compressed by the compressing means 41 to the outside of the housing portion 30; an expanding means 43 of expanding the refrigerant liquefied by the condensing means 42; an evaporating means 44 of evaporating the refrigerant expanded by the expanding means 43 by receiving the heat from the functional element 36; and a blowing means 45. Length directions of the condensing means 42 and compressing means 41 are substantially parallel with a side face of the housing portion 30. Consequently, the condensing means 42 and compressing means 41 which are relatively large-sized components can be stored compactly, so the space that the cooling device occupies in the housing is reducible.
