A sensor shifting actuator includes a sensor substrate on which an image sensor having an imaging surface is disposed; a base configured to accommodate the sensor substrate; and a driver configured to drive the image sensor in a first direction and a second direction, parallel to the imaging surface. The sensor substrate includes a movable portion on which the image sensor is disposed, a fixed portion coupled to the base, and a connection portion disposed between the movable portion and the fixed portion. Depending on a movement direction of the image sensor in the first direction or the second direction, the movable portion and the connection portion relatively move with respect to the fixed portion, or the movable portion relatively moves with respect to the connection portion.
