PROBLEM TO BE SOLVED: To provide a control board which can sufficiently radiate heat even when a heat quantity of an electronic apparatus is high.SOLUTION: A control board according to the present invention includes: an air-tight case which has an electronic apparatus housing section in which a high-temperature air dedicated passage and a low-temperature air dedicated passage are formed; and a ventilation cooling section which is provided on a side closer to the high-temperature air dedicated passage than the low-temperature air dedicated passage of the air-tight case via a side wall of the air-tight case and has a dust-proof electronic apparatus housing section. Heat can be sufficiently radiated even when a heat quantity of an electronic apparatus is high because a heat quantity in the air-tight case can be made low by housing a dust-proof electronic apparatus in the ventilation cooling section provided in the outside of the air-tight case. Since the electronic apparatus disposed in the low-temperature air dedicated passage is suppressed from being heated by the high-temperature air of the dust-proof electronic apparatus housing section by providing the dust-proof electronic apparatus housing section on a far side from the low-temperature air dedicated passage of the electronic apparatus housing section, heat can be sufficiently radiated even when the heat quantity of the electronic apparatus is high. |
