A vehicle heater (10) comprises a main body (12) carrying a non-intrinsically safe heat conductor layer (14), and a sensor device (16, 18, 20) allocated to the heat conductor layer (14) and provided to detect an exceedance of a temperature threshold value. The sensor device (16, 18, 20) comprises a sensor layer arranged on the side of the heat conductor layer (14) (16) facing away from the main body (12) which is monitored for current flows which may occur substantially in the direction of its surface normal (42). In a method for producing a vehicle heater (10) a main body (12) of the vehicle heater (10) is equipped with a non-intrinsically safe heat conductor layer (14), and a sensor device (16, 18, 20) for detecting exceedances of a temperature threshold value. A sensor layer (16) provided to be monitored for current flows which may occur substantially in the direction of the surface normal (42) of the sensor layer (16) is allocated to the heat conductor layer (14) on its side facing away from the main body to form the sensor device (16, 18, 20). |
