The dual camera module according to the first modification example omits the fourth magnet unit 1420 compared to the dual camera module according to the present embodiment. Therefore, the description of the remaining configurations of the dual camera module according to the first modification, excluding the fourth magnet unit 1420, can be inferred from the description of the dual camera module according to the present embodiment. As in the first modification, the fourth magnet unit 1420 may be omitted and only the third magnet unit 1410 may be provided. In this case, the size of the third magnet unit 1410 may be different compared to the present embodiment.

You can.

The dual camera module according to the second modification omits the third and fourth magnet units 1410 and 1420 compared to the dual camera module according to the present embodiment. Therefore, the description of the remaining configurations of the dual camera module according to the second modification, excluding the third and fourth magnet units 1410 and 1420, can be inferred from the description of the dual camera module according to the present embodiment. . In the dual camera module according to the second modification, the flat magnet of the AF camera module may have an influence on the corner magnet of the OIS camera module due to the omission of the third magnet unit 1410. Therefore, in the second modification, the AF camera module and the OIS camera module can be spaced further apart than in the present embodiment. Meanwhile, in the second modification, when compared to the case where a flat magnet of the same size as the first magnet 1321 is disposed on the second side 1302 of the first housing 1310, the flat magnet of the AF camera module is connected to the OIS camera. It can be seen that the impact on the corner magnet of the module has been reduced.
