A micromechanical structure includes: a substrate; a seismic mass movable relative to the substrate along a first direction parallel to a main plane of extension of the substrate; a first electrode structure is connected to the substrate; and a second electrode structure connected to the substrate. The seismic mass includes a counterelectrode structure having finger electrodes situated between first finger electrodes of the first electrode structure and second finger electrodes of the second electrode structure, along the first direction. The first electrode structure is fastened to the substrate by a first anchoring element in a central region of the micromechanical structure, and the second electrode structure is anchored to the substrate by a second anchoring element situated in the central region.
