1. A lens moving apparatus comprising:
a housing;
a bobbin disposed in the housing;
a coil coupled to the bobbin;
a magnet disposed on the housing so as to face the coil;
a base disposed so as to be spaced apart from the bobbin and comprising a first side portion, a second side portion opposite to the first side portion, a third side portion between the first side portion and the second side portion, a fourth side portion opposite to the third side portion, a first projection located at a first corner portion between the first and third side portions thereof, and a second projection located at a second corner portion between the first and fourth side portions thereof;
a lower elastic member coupled to the bobbin and comprises a first elastic member and a second elastic member, disposed on the base;
a first sensing coil disposed on the housing and generates a first induction voltage through interaction with the coil;
a second sensing coil disposed on the base and generates a second induction voltage through interaction with the coil;
first to fourth terminals coupled to the base and are spaced apart from the first and second elastic members;
a first connecting terminal connecting the first elastic member; and
a second connecting terminal connecting the second elastic member,
wherein on end of the coil is coupled to the first elastic member and a remaining end of the coil is coupled to the second elastic member,
wherein the first terminal includes:
a first body located on the first side portion of the base; and
a first extension extending from the first body, the first extension having a portion located in the first corner portion of the base,
wherein the second terminal includes:
a second body located on the first side portion of the base; and
a second extension extending from the second body, the second extension having a portion located in the second corner portion of the base,
wherein a distal end of the portion of the first extension is exposed from an upper surface of the first projection of the base, and a distal end of the portion of the second extension is exposed from an upper surface of the second projection of the base, and
wherein one end of the first sensing coil is coupled to the distal end of the portion of the first extension and a remaining end of the first sensing coil is coupled to the distal end of the portion of the second extension.
