摘要

To provide a computer device wherein liquid penetration into a ventilation hole from its periphery can be prevented or reduced without sacrificing design and without limitation of the size and operation.Coating films 7a and 7b in frame form are applied on a periphery of a ventilation hole 6. A wet-characteristic of the coating film 7a and 7b is different from a wet-characteristic of material composing a housing 3. For example, when an angle of contact of coating films 7a and 7b for water is larger than an angle of contact of material composing the housing 3, if water is spilled on the outside of the coating film 7b the coating film 7b prevents the water flow into the ventilation hole 6.
