PURPOSE: An electronic device is provided to prevent the separation of key rubber by controlling the key rubber through a front case. CONSTITUTION: A case comprises a fixing unit. A print substrate(140) is fixed to the fixing unit. Key rubber(172) is fixed to the print substrate. The key rubber comprises a plurality of key tops(174). A flexible cable(148) is installed to the print substrate. The key rubber comprises a contact unit(172f) receiving repulsive power of the flexible cable, and a holder(172g) which is pressed to the case by the repulsive power. The holder comprises an elastic member. A surface shape unit(172b) faces to a metal dome(132). A supporting unit(172a) securely supports the surface shape unit. |
