摘要
A thermal gas sensor for measuring the thermal diffusivity and/or the thermal conductivity of a gas or gas mixture includes a substrate. In the surface of the substrate a trench is formed, as well as at least two conductor structures arranged at a distance from one another on the surface of the substrate. The conductor structures respectively each contain at least two contact sections and a web section connected to the contact sections, the web sections of the conductor structures crossing over the trench at a distance from one another. At least one slot is formed between at least two contact sections of different conductor structures in at least one region of the surface of the substrate.
