The curvature of the grooves 1330 and 1340 may be different from the basic curvature generated on the edge processing. The shapes of the first corner portion and the second corner portion of the magnet 1320 may be different from those of the third corner portion and the fourth corner portion of the magnet 1320. [ In one example, the basic curvature is convexly formed, but the grooves 1330 and 1340 may be concave.

The dual camera module according to the present embodiment may include a first groove 1330 formed in the magnet 1320. In this embodiment, the influence of the magnetic force applied to the second camera module by the magnet 1320 of the first camera module through the first groove 1330 can be minimized. The first trench 1330 according to the present embodiment can be distinguished from the natural curvature generated at the corners in the manufacturing process of the magnet 1320 in terms of shape, size, and function. In this embodiment, the shape of the magnet 1320 of the first lens driving apparatus 1000 closer to the second lens driving apparatus 2000 is referred to as 'R cut', 'C cut', 'A cut' or 'B cut' Can be processed. Alternatively, in the present embodiment, the shape of the magnet 1320 of the first lens driving device 1000 near the second lens driving device 2000 can be roundly cut.

In this embodiment, the influence of the magnetic force on the second lens driving apparatus 2000 can be minimized by adjusting the position of the magnet 1320 of the first lens driving apparatus 1000. In more detail, the magnet coupling portion 1312 of the housing 1310 of the first lens driving apparatus 1000 may be biased toward the center line. That is, the magnet 1320 may be biased to one side with respect to the center of the coil 1220 (see C in FIG. 7).

In the present embodiment, when only the first groove 1330 is provided in the magnet 1320 without the second groove 1340, magnetic imbalance of the magnet 1320 may occur due to the bias of the magnet 1320 relative to the center of the coil 1220 have. This may cause a problem because it causes a tilt of the first lens driving apparatus 1000. More specifically, in the present embodiment, when only the first trench 1330 is provided without the second trench 1340 in the magnet 1320, the first trench 1330 is formed around the center of the coil 1220 (See 1320a in FIG. 16) on the side where the first and second split magnets 1330 and 1330 are formed has a magnetic force of 0.00090476 (N) and the divided magnet on the opposite side has a magnetic force of 0.0010575 (N). The present embodiment may include a structure in which the shape of the chamfer is added where the magnetic force of the magnet 1320 strongly occurs with respect to the center of the coil 1220 so that the left and right electromagnetic force deviations are set to zero. The chamfer shape may be referred to as a second groove portion 1340. That is, in this embodiment, the deviation of the magnetic force of the magnet 1320 through the second trench 1340 can be eliminated or minimized. More specifically, according to the application of the second trench 1340, the divided magnet (see 1320b in Fig. 16) on the side where the second trench 1340 is formed with respect to the center of the coil 1220 has a magnetic force of 0.0009066 (N) So that the left-right deviation electromagnetic force can be close to zero. 7 and 16 are schematic diagrams of the second lens driving apparatus 2000, and B shown in Figs. 7 and 16 is an example in which the terminal portion 1524 of the lower elastic member 1520 is disposed Direction (pin direction, terminal direction). That is, the second magnet 1322 may be disposed on the terminal portion 1524 side of the lower elastic member 1520. In the present embodiment, the second groove portion 1340 can also be processed into 'R-cut', 'C-cut', 'A-cut', or 'Cut'. Or the second groove portion 1340 may be roundly cut.

In this embodiment, since the left and right electromagnetic force deviations of the magnet 1320 are minimized through the second trench 1340, the occurrence of tilt can be minimized. The embodiment shown in FIG. 17 is a comparative example in which the second groove portion 1340 is not provided, and the embodiment shown in FIG. 18 includes the second groove portion 1340 in this embodiment. 17 and FIG. 18, it can be seen that the tilt is reduced through the second trench 1340.
