The invention provides a monolithic integrated three-axis accelerometer and a manufacturing method thereof so as to solve the defects in structure and manufacturing technology of the existing structural capacitive accelerometer. Three layers of metal Al thin films are deposited in the direction of an axis Z so as to form a comb pair sensitive electrode; four layers of metal Al / SiO2 thin films are deposited in the directions of an axis X and an axis Y so as to form comb pair sensitive electrodes, and the accelerations of the three axis directions are detected simultaneously by a single integrated structure. The accelerometer and the manufacturing method thereof have the following positive technical effects: the interconnection stray capacitance among accelerator devices in three axis directions is lowered remarkably, and high detection accuracy and lower noise performance are realized; since the accelerometer is provided with the multiple metal layers, compared with a microaccelerometer manufactured from the same material, namely polycrystalline silicon, the accelerometer is more flexible in wiring; a foldable beam is used in the structure of the accelerometer, so that the own stress of the accelerometer is released better, and therefore the influence of the stress on the system can be reduced effectively.
