An electronic apparatus has a plurality of basic structures arranged adjacent to each other in a direction perpendicular to a gravitation direction. Each of the basic structures includes a casing, a board placed parallel to the gravitation direction inside the casing, a first space with large ventilation amount and a second space with small ventilation amount formed by the board dividing the inner space of the casing, vents in the upper and lower surfaces of the casing, an electronic component placed on the board in the first space, and an electronic component placed on the board in the second space. The casings of adjacent basic structures are in communication through inner vents in respective side walls of the casings, and external vents in communication with the outside are provided in left and right side walls of the electronic apparatus. |
