    摘要： Embodiments of the invention provide a MEMS sensor, including a flexible substrate having a vibrator and a sensor, a mass body coupled with the flexible substrate, and a support part supporting the flexible substrate. The vibrator includes a multilayer piezoelectric part and an electrode part connected to the multilayer piezoelectric part, and the sensor includes a piezoelectric material and an electrode part. The multilayer piezoelectric part is polled in the same direction and one of the piezoelectric materials contacting each other is expanded or contracted in an opposite direction to the other piezoelectric material. An uppermost layer of the vibrator and an uppermost layer of the sensor with respect to a stacking direction in which the piezoelectric material and the electrode part of the vibrator and the sensor are each stacked, are disposed on the same surface.
