An electric apparatus includes a centrifugal fan (5) that includes an impeller (5d) in a casing (5c), and draws air when the impeller rotates in the casing, and has a blowoff channel of the air from the impeller in the casing, which spreads in a rotating direction of the impeller, and a first cooled part (50R, 50B, 59R, 59B) and a second cooled part (50G, 59G) that has a necessary cooling air capacity larger than that of the first cooled part, the first cooled part and the second cooled part being cooled by the air drawn by the centrifugal fan, wherein a drawing surface (5a) of the centrifugal fan has a first drawing area (A area) and a second drawing area (B area) that has a drawing speed higher than that of the first drawing area when the impeller rotates.
