Thin type key set faceplate is installed inside electronic equipment. The structure uses as main body. The basal plate made from plastic material. Transparent thin film layer is setup at back face of the basal plate. The thin film layer is made from rubber material. Multiple contact ends with interval between them are setup at the thin film layer. Through interactive structure of the basal plate and the thin film layer, when the structure of basal plate is pushed by outside force, the basal plate enhances tensile force of the thin film layer so as to retain structural integrality of the thin film layer and entire key set faceplate.
