description A dustproof structure for a communication device is disclosed, in which the whole area of the air filter can be effectively used, the dust collecting efficiency can be improved at low cost, and an increase in the pressure loss can be prevented. The air filter comprises a first air filter section and a second air filter section, wherein the first air filter section is provided at an area closer to the fan, within which the air flow is concentrated, and the second air filter section is provided at another area farther from the fan, and the first air filter section has a dust collecting efficiency higher than that of the second air filter section, while the second air filter section has a pressure loss lower than that of the first air filter section.
