1. A method for producing a heater with a co-sintered multilayer construction for a system for providing an inhalable aerosol, the method comprising:
providing at least one first substrate layer;
arranging at least one first insulating layer at least in areas on the first substrate layer;
arranging at least one heating element at least in areas on the first insulating layer, arranging at least one second substrate layer and at least one second insulating layer at least in areas on the at least one heating element, wherein the at least one second insulating layer is arranged at least in areas on the at least one second substrate layer, and wherein the at least one second insulating layer is in contact at least in areas with the at least one heating element and/or with the at least one first insulating layer;
pressing the layers and the heating element; and
firing the pressed layers in order to co-sinter the layers of the multilayer construction.
