PROBLEM TO BE SOLVED: To provide a telecommunication equipment for which cleaning work of an air filter for air cooling or the like can be performed even in a small place. SOLUTION: For this telecommunication equipment, a plurality of circuit packages for which many electronic components are mounted on a substrate can be housed inside a case body. Two air filters having a depth length slightly longer than a half of the depth length of the case body are arranged up and down at a bottom of the case body, the air filter on a lower side is provided with a roller, the case body is provided with a guide guiding the roller, and the air filter on an upper side is arranged in contact with the roller so as to be movable in a horizontal direction accompanying rotation of the roller. Thus, by making the upper side filter movable as well following the movement by a pulling-out/housing operation to the case body of the lower side air filter, the respective filters are attached and detached.
