Therefore, the size of the sensor driving device can be reduced and power consumption can be reduced. Furthermore, the power consumption of the sensor driving device can be reduced due to the symmetrical structure of rigidity. Therefore, the size of the camera module 10 can be reduced and power consumption can be reduced.
