For example, the thickness of the filter 610 may be the length of the filter 610 in the optical axis direction.

The lower surface 61a of the filter 610 may be higher than or at the same height as the lower surface 51b of the holder 600 , but is not limited thereto.

Also, for example, the upper surface 61a of the filter 610 may be positioned higher than the second edge 9B of the holder 600 based on the upper surface of the image sensor 810 or the upper surface of the circuit board 800 .

In another embodiment, the upper surface 61a of the filter 610 may be positioned lower than the second edge 9B of the holder 600 .

Referring to FIG. 6B , the first adhesive member 310 is disposed between the first area 55A of the outer surface of the filter 610 and the first surface 3A of the inner surface 4 of the holder 600 . A first portion 31-1, and a second portion disposed between the second area 55B of the outer surface of the filter 610 and the second surface 3B of the inner surface 4 of the holder 600 ( 31-2) may be included.

The first portion 31-1 of the first adhesive member 310 connects the first surface 3A of the inner surface 4 of the holder 600 and the first area 55A of the outer surface of the filter 610 to each other. It can be connected, and the first surface 3A and the first region 55A can be attached to or fixed to each other.

For example, the horizontal length of the first portion 31-1 of the first adhesive member 310 may increase from the lower surface 51b to the upper surface 51a of the holder 600 . Also, for example, the length of the second portion 31 - 2 of the first adhesive member 310 in the horizontal direction may be uniform or constant.

In another embodiment, at least one protrusion (not shown) facing the outer surface of the filter 610 may be formed on at least one of the first surface 3A and the second surface 3B of the holder 600 .

The first surface 3A of the inner surface 4 of the holder 600 has an inclined surface structure, and since d1 gradually increases from the lower surface 51b to the upper surface 51a direction of the holder 600, the first adhesive member ( 310 can be easily injected between the inner surface 4 of the holder 600 and the outer surface of the filter 610 .

The holder of a general camera module overlaps the filter and at least a part in the optical axis direction and has a support for supporting the filter, but such a camera module has the following limitations.

First, the thickness of the camera module may be limited by the thickness of the camera module in the optical axis direction when designing the camera module by the thickness of the support. For example, the thickness of the support may be about 0.17 mm.

In addition, the separation distance between the image sensor and the lens module may be reduced, thereby reducing the degree of freedom of lens selection. In addition, the distance between the filter and the lens module is reduced, and thus, a stroke of the lens driving device in the optical axis direction may be restricted, and it may be difficult to secure reliability of AF driving.

In the embodiment, since the adhesive force between the filter 610 and the holder 600 increases, the filter 610 by the first adhesive member 310 even if the holder 600 does not include a support for supporting the filter 610 . ) can be stably attached and fixed to the holder 600 .

In addition, since the holder 600 does not have a support that overlaps the filter 610 in the optical axis direction, the embodiment can increase the height margin of the camera module in the optical axis direction, and the separation distance between the image sensor and the lens module is By preventing shrinkage, the degree of freedom of lens selection can be improved. For example, the embodiment may secure a height margin in the optical axis direction as much as the thickness (about 0.17 mm) of the support.

In addition, since it is possible to secure a sufficient distance between the filter 610 and the lens module 400, the embodiment can suppress the restriction of the stroke of the lens driving device in the optical axis direction when the thickness of the filter 610 is thick. Therefore, the reliability of AF driving can be improved.

For example, the thickness of the filter 610 of the camera module according to the embodiment may be 0.2mm or more. For example, the thickness of the filter 610 may be 0.2 mm or more and 5 mm or less. For example, the thickness of the filter 610 may be 0.2 mm or more and 1 mm or less. Alternatively, for example, the thickness of the filter 610 may be 0.4 mm or more and 1 mm or less.

For example, the filter 610 may be a glass filter.

7 is a cross-sectional view of a portion of the camera module 200 according to another embodiment, and FIG. 8 is an enlarged view of the dotted line portion 11 of FIG. 7 . In FIG. 8 , the first adhesive member 310 is omitted.

7 and 8 , the lower surface 61b of the filter 610 may be higher than the lower surface 51b of the holder 600 and lower than the second edge 9B of the holder 600 . Also, the upper surface 61a of the filter 610 may be lower than the upper surface 51a of the holder 600 and higher than the second edge 9B of the holder 600 .

For example, the lower surface 61b of the filter 610 may be positioned higher than the third edge 9C of the inner surface 7 of the holder 600 and lower than the second edge 9B of the holder 600 . In addition, the upper surface 61a of the filter 610 may be positioned lower than the first edge 9A of the holder 600 and higher than the second edge 9B of the holder 600 . For example, the third corner 9C may be a portion where the second surface 3B of the inner surface 7 of the holder 600 meets the lower surface of the holder 600 .

The thickness of the filter 610 may be smaller than the distance h1 from the lower surface 51b to the upper surface 51a of the holder 600 .

d1 may be a distance between the outer surface of the filter 610 and the first surface 3A of the inner surface 4 of the holder 600 . For example, d1 may be a distance between the first area 55A of the outer surface of the filter 610 and the first surface 3A of the inner surface 4 of the holder 600 . d1 may gradually increase from the lower surface 51b to the upper surface 51a of the holder 600 .

For example, d1 may be 0.4 [mm] to 0.6 [mm]. For example, d1 may be 0.4 [mm] to 0.5 [mm]. Considering the size of the needle (needle) of the adhesive injector for injecting the first adhesive member 310, d1 is preferably greater than 0.4 [mm]. This is because when d1 is less than 0.4 [mm], the first adhesive member 310 cannot be easily and smoothly applied to or injected into the inner surface 4 of the holder 600 . In addition, when d1 is greater than 0.6 [mm], the distance between the filter 610 and the first surface 3A of the inner surface 4 of the holder 600 is too large to increase the size of the holder, and the first The amount of the adhesive member used may be increased.

Also, d2 may be a distance between the outer surface of the filter 610 and the second surface 3B of the inner surface 4 of the holder 600 . For example, d2 may be a distance between the second area 55B of the outer surface of the filter 610 and the second surface 3B of the inner surface 4 of the holder 600 .

For example, d2 may be uniform or constant from the lower surface 51b of the holder 600 to the second edge 9B.

For example, d2 may be 0.05 [mm] to 0.15 [mm]. For example, d2 may be 0.05 [mm] to 0.1 [mm]. When d2 is less than 0.05 [mm], the separation distance between the outer surface of the filter 610 and the inner surface of the holder 600 may be too small, which causes the holder 600 and the filter 610 by external impact. A collision may occur between them, and at least one of them may be damaged.

On the other hand, when d2 is greater than 0.15 [mm], the size of the holder 600 may increase to increase the size of the camera module according to the embodiment.

In addition, the numerical range of d2 is a range in consideration of shifting the center of the filter 610 when assembling the holder 600 and the filter 610 , in consideration of the bonding area of the first adhesive member 310 . For example, when d2 is less than 0.05 [mm], the area of the first adhesive member 310 positioned between the inner surface of the holder 600 and the outer surface of the filter 610 may not be sufficient to stably bond the two. have. On the other hand, when d2 is greater than 0.15 [mm], the amount of the first adhesive member 310 may be excessively increased.

The length (or height h2) in the optical axis direction of the first surface 3A, which is an inclined surface from the inner surface 4 of the holder 600, may be less than or equal to the thickness (or height) of the filter 610. have.

Since the holder 600 according to the embodiment does not have a support portion overlapping the filter 600 in the optical axis direction, the separation distance between the filter 600 and the lens module 400 may be increased. Due to this, the restriction on the thickness of the filter 610 can be relaxed, and even when the thick filter 610 is used, it is possible to suppress the restriction of the stroke of the lens driving device in the optical axis direction, so that the reliability of AF driving can be suppressed. can improve
