Abstract
In a micromechanical sensor () for measuring a mass flow rate in accordance with the Coriolis principle, two line sections () are mounted in a suspension means () such that they can oscillate, as a result of which they can be caused to oscillate in phase opposition (essential for the measuring principle). A spacer layer () is provided between the layers () forming the line sections (), the spacer layer ensuring that there is a space between the line sections () in the quiescent state. Oscillation of the line sections in phase opposition only becomes possible at all as a result of this since this prevents collision of the line sections () as they approach one another.
