A lens driving apparatus, comprising:
- a first frame which accommodates a lens;
- a driver, connected to the first frame, and configured to generate a driving force to move the first frame in a first direction;
- and
- a group of rolling members comprising at least one multi-layered rolling member including two or more different materials,
- wherein the group of rolling members at least partially contacts the first frame,
- wherein the at least one multi-layered rolling member comprises a core part and an outer part that surrounds the core part, and wherein the outer part is formed of a material that is different from a material of the core part, and
- wherein the material of the core part has a lower modulus of elasticity than a modulus of elasticity of the material of the outer part.

A camera module, comprising:
- a lens;
- a first frame which accommodates the lens;
- a second frame disposed below the first frame;
- a driver, connected to the first frame, and configured to generate a driving force to move the first frame in a first direction;
- and
- a plurality of rolling members that is disposed between the first frame and the second frame and at least partially contacts the first frame,
- wherein at least one of the plurality of rolling members is a multi-layered rolling member including two or more different materials,
- wherein the at least one multi-layered rolling member comprises a core part and an outer part that surrounds the core part, and wherein the outer part is formed of a material that is different from a material of the core part, and
- wherein the material of the core part has a lower modulus of elasticity than a modulus of elasticity of the material of the outer part.
