the elastic member has a protrusion shape extending from both surfaces of the plate in the first direction and the second direction.
10 . The camera module of claim 8 , wherein the plate is formed of a metal material, and
the elastic member is formed of an elastomer.
11 . The camera module of claim 8 , wherein the elastic member is configured to come into contact with or be spaced apart from the first fixing portion or the second fixing portion as the lens assembly moves.
12 . The camera module of claim 8 , wherein the shock mitigation member comprises an elastic body comprising one end fixed to the plate and extending in a direction toward the lens assembly from the one end fixed to the plate.
13 . A camera module comprising:
a frame;
a lens assembly configured to receive at least one lens and comprising a recess or an opening disposed on one side thereof;
an actuator configured to move the lens assembly in a direction parallel to an optical axis of the at least one lens; and
a shock mitigation member is configured to protrude from the frame into the recess or the opening to be at least partially received in the recess or the opening,
wherein the shock mitigation member is configured to come into contact with one side of the recess or the opening by movement of the lens assembly.
14 . The camera module of claim 13 , further comprising a fixing portion configured to limit a movement range of the lens assembly by contacting with the lens assembly by movement of the lens assembly,
wherein the shock mitigation member is configured to come into contact with the one side of the recess or the opening before the lens assembly comes into contact with the first fixing portion or the second fixing portion.
15 . The camera module of claim 12 , wherein the shock mitigation member comprises a cantilever-shaped plate having one end fixed to the frame and other end to which an elastic member is coupled.
