Abstract: An electromagnetic wave suppression material is fixed to a case of a communication module. The electromagnetic wave suppression material suppresses radiation of electromagnetic waves by coming into contact with a cage that is a module insertion portion of a chassis when the communication module is inserted into the cage. A piezoelectric element is provided on the case, and located between the case and the electromagnetic wave suppression material. When the communication module is inserted into the cage, the controller applies a voltage to the piezoelectric element to stretch it by the applied voltage, thereby increasing contact pressure between the cage and the electromagnetic wave suppression material.
