A slot-closing device for closing a slot in a stator or a rotor of an electric machine includes a closure element which contains a ferromagnetic material. An adhesive layer disposed on the closure element is designed to expand and harden when heated. The adhesive layer contains a thermally activatable blowing agent configured as an expansion element which contains a closed cavity filled with gas. The cavity is partially enclosed by a thermoplastic resin in the expansion element.
