ABSTRACT:
A cooling device (5) has a frame (51) as a chassis having a fan body (511) thereinside and a base portion (52) formed on the upper side of the frame (51), the frame (51) and the base portion (52) being made of a heat-conductive material. An object (44) to be cooled is fixed on the base portion (52) and heat is conducted from the object (44) to the base portion (52) where the conducted heat is radiated. The fan body (511) provided on the cooling device (5) blows a cooling air to cool the object (44). Accordingly, the heat on the object (44) is cooled by the cooling air blown by the fan body (511) and also by the heat-radiation by a heat radiator on the cooling device (5).
