Abstract
A particle sensor for detecting electrically conductive particles. The particle sensor includes a first electrode structure with at least one electrode and a second electrode structure with at least one electrode. The first electrode structure and the second electrode structure are situated on an electrically insulating base body. An electric potential difference is generatable between an electrode of the first electrode structure and an electrode of the second electrode structure. The base body includes a heating structure for heating the first electrode structure and the second electrode structure, the heating structure being at least partially enclosed by the base body. This makes it possible to protect the heating structure and also to reduce the voltage needed to burn off particles accumulated on the electrode structures. A method for manufacturing a particle sensor is also described.
