Electronic device

An electronic device comprising:

• a sealable housing to seal against an external environment of the electronic device, the housing including constituent surfaces that are configured by a thermal conductor;
• a plurality of heat generating components including a high-heat generating component having a relatively large heating value during operation and a low-heat resistant component having a heating value during operation relatively smaller than the heating value of the high-heat generating component and having a heatproof temperature lower than that of the high-heat generating component, the heat generating components being housed on an inside of the housing;
• and
• a blower housed on the inside of the housing, wherein
• the low-heat resistant component is housed above the high-heat generating component,
• the blower sends wind, in a state in which the wind does not hit the high-heat generating component, from one side surface side of two side surfaces opposed to each other in the housing to the other side surface side between the high-heat generating component and the low-heat resistant component to thereby blow the wind between the low-heat resistant component and the high-heat generating component including heat generated by the high-heat generating component against the other side surface using the wind, and
• a part of the wind between the low-heat resistant component and the high-heat generating component blown against the other side surface circulates to the one side surface side and is blown from the one side surface side toward the other side surface by the blower.
