Abstract

A method for producing an ultrasound sensor for a vehicle is disclosed. A diaphragm for emitting ultrasound signals in an emitting direction and a sensor housing are provided for the sensor, where the diaphragm is fastened on the sensor housing, where the housing has a front side, which points in the emitting direction, and a rear side, which points opposite the emitting direction, and where, on the front side, the housing is formed with a front-side opening for the diaphragm, where the front side of the housing is connected to a cap which is composed of a foil and by way of which the front-side opening of the housing is covered in the emitting direction, where the diaphragm is inserted at least regionally into a receptacle of the cap and, a front side of the diaphragm, which points in the emitting direction, is connected to a base of the receptacle.
