Camera actuator and camera module comprising same

A camera actuator comprising:

• a first housing;
• a prism unit disposed within the first housing;
• and
• a first driving portion for tilting the prism unit in a first axis or a second axis,
• wherein the prism unit includes a prism mover having a receiving space, and a prism disposed and fixed in the receiving space of the prism mover,
• wherein the first driving portion includes a first magnet disposed on a region corresponding to a first outer surface of the prism unit;
• a second magnet disposed on a region corresponding to a second outer surface opposite to the first outer surface of the prism unit;
• and a third magnet disposed on a region corresponding to a third outer surface disposed between the first and second outer surfaces of the prism unit,
• wherein the prism unit includes a fifth outer surface disposed between the first and second outer surfaces and connected to the third outer surface,
• wherein the first and second magnets are spaced apart in a first direction,
• wherein centers of the first and second magnets based on the first direction are arranged on a same line,
• wherein a center of the third magnet based on a second direction perpendicular to the first direction is disposed closer to a fifth outer surface than an imaginary straight line connecting the centers of the first and second magnets.
