A keyboard apparatus is able to be made thinner without sacrificing ease of operation or feel. The keyboard apparatus is less expensive and permits easier assembly. Through holes are formed in a metal plate at the locations where retaining members are to be installed, then the resinous retaining members are inserted in the through holes to be mounted on the metal plate. For this purpose, the retaining members are formed by a molding method referred to as an outsert molding method. Supporting members are shaped so that they may be snapped in the retaining members. The retaining members are combined with a membrane switch, the supporting members, a key top, and an elastic member.
