A membrane switch comprises a pair of flexible sheets connected together with the respective inner surfaces thereof provided with contacts and terminals respectively connected to the contacts facing each other and spaced apart by a spacer, and an output flat cable held between the pair of flexible sheets with the leader lines thereof in electrical contact respectively with the terminals. One of the contacts is formed on the inner surface of one of the pair of flexible sheets by evaporation and etching. The rest of the contacts are formed on the inner surface of the other flexible sheet by evaporation and etching. A connecting film is formed over the periphery of the inner surface of at least one of the pair of flexible sheets. Portions of the connecting film corresponding to the terminals are formed of films of an electrically conductive adhesive or heat sealing material, and portions of the connecting film other than those corresponding to the terminals are formed of films of an electrically insulating adhesive or heat sealing material.
