Abstract

A sensor element includes a sensor arrangement and a heating arrangement. The sensor arrangement can be heated by the heating arrangement. The heating arrangement has an electrically conductive heating structure which is at least partially electrically insulated from the sensor arrangement by electrical insulation having an electrically insulating material. The electrically insulating material has gas-tight sintered particles which have forsterite particles, spinel particles, or a mixture of forsterite particles and spinel particles. Such particles may have an average size D50 of less than or equal to about 200 nm.
