A device for measuring the mass of a flowing medium having a temperature-dependent sensor element, which is inserted flush in a recess of a sensor carrier and is retained therein by means of an adhesive. The sensor carrier is made by bending a thin metal strip and has two elements, a frame element and a retaining element, which together form a recess, into which the sensor element is inserted flush and glued by means of an adhesive to a plateau-like protuberance of a bottom face of the retaining element. The sensor carrier is intended for a device for measuring the mass of a flowing medium for measuring the flow rate or mass of the air aspirated by internal combustion engines.
