1. A lens moving apparatus comprising:
a bobbin;
a first coil coupled to the bobbin;
a magnet opposite the first coil;
a base disposed spaced apart from the bobbin;
a lower elastic member coupled to the bobbin, the lower elastic member comprising a first elastic member and a second elastic member disposed on the base;
a second coil disposed on the base, the second coil being configured to generate induced voltage through interaction with the first coil; and
a first terminal and a second terminal coupled to the base, the first terminal and the second terminal being spaced apart from the first and second elastic members,
wherein a first portion of the first coil is coupled to the first elastic member and a second portion of the first coil is coupled to the second elastic member,
wherein each of the first and second terminals comprises:
a first portion exposed from an upper surface of the base; and
a second portion connected to the first portion, the second portion being bent in a lateral direction of the base, and
wherein a first portion of the second coil is coupled to the first portion of the first terminal and a second portion of the second coil is coupled to the first portion of the second terminal.
