Since the adhesive material 140 'has fluidity before curing, the lens barrel 110, which is seated on the adhesive material before curing, has a third seating portion P3 of the lens barrel 110 in the through hole 131 In the inserted state, it can be tilted.

For example, when the lens barrel 110 is in contact with the adhesive material 140 ', the lens barrel 110 is moved to adjust the focus of the lens array 120 mounted on the lens barrel 110 with respect to the image sensor 160 .

For example, the lens barrel 110 may be moved forward, backward, left, or right to adjust the focal point of the lens array 120 mounted on the lens barrel 110 from the first focus f1 to the second focus f2 as a desired target focus . In this way, the lens barrel 110 is directly moved to adjust the focus of the lens array 120 is referred to as "active alignment ".

The projecting portion of the lens barrel 110 inserted into the through hole 131 for the active alignment such as the outer circumferential surface 139 of the third seating portion P3 is spaced from the inner circumferential surface 119 of the through hole 131 .

The outer circumferential surface 139 of the third seating portion P3 of the lens barrel 110 inserted into the through hole 131 is brought into contact with the inner circumferential surface 119 of the through hole 131 or the third seating portion P3 are coupled to the inner circumferential surface 119 of the through hole 131 by a screw or the like, the lens barrel 110 can not be moved and active alignment can not be performed.

Next, as shown in FIG. 7, the focus of the lens array 120 is aligned with the target focus through the active alignment, and then the adhesive material is cured by thermosetting or UV curing to form the first adhesive member 140 .

8 shows a first adhesive member 140-1 according to another embodiment.

Although the first adhesive member 140 shown in Fig. 5 has a ring shape, the adhesive member 140-1 shown in Fig. 8 has an opening (opening) 501 in which a part of the first adhesive member 140 in the ring shape is removed .

The first adhesive member 140 includes one end 11a and the other end 11b arranged to surround the through hole 131. One end 11a and the other end 11b of the first adhesive member 140 are connected to each other It is separated. For example, the first adhesive member 140 may be in the shape of a ring having an opening 501 in the lateral direction, which is located between one end 11a and the other end 11b that are spaced apart from each other. Here, the lateral direction may be the direction from the inner circumferential surface to the outer circumferential surface of the first adhesive member 140 and / or the opposite direction.

For example, one end of the opening 501 can be opened to the inner circumferential surface of the first adhesive member 140, and the other end of the opening 501 can be opened to the outer circumferential surface of the first adhesive member 140.

For example, the distance between one end 11a and the other end 11b of the first adhesive member 140 may gradually increase from the inner peripheral surface to the outer peripheral surface of the first adhesive member 140, But is not limited thereto. The distance between one end 11a and the other end 11b of the first adhesive member 140 may be constant in the direction from the inner circumferential surface to the outer circumferential surface of the first adhesive member 140. [ For example, the distance between one end 11a and the other end 11b of the first adhesive member 140 can be expressed as W1, which is the width of the opening 501 in FIG.

The total length of the first adhesive member 140 may be longer than the distance between the one end 11a and the other end 11b of the first adhesive member 140. [ For example, the distance between one end 11a and the other end 11b of the first adhesive member 140 may be less than 1/4 of the total length of the first adhesive member 140. When the distance between one end 11a and the other end 11b of the first adhesive member 140 exceeds 1/4 of the total length of the first adhesive member 140, the adhesion performance of the first adhesive member 140 This is because the lens barrel 110 and the holder 130 can be separated from each other.

When thermally curing or UV curing the adhesive material 140 ', gas may be generated from the adhesive material 140'.

5, after the protrusion of the lens barrel 110 is inserted into the through hole 131 of the holder 130 in a state where the circuit board 150 and the holder 130 are coupled, the first adhesive member 140 The holder 130 and the circuit board 150 can be a sealed structure because the lens barrel 110 and the holder 130 are joined by the lens barrel 110 and the lens barrel 110. [

5, since the gas generated during the thermal curing or UV curing of the first adhesive member 140 is a sealed structure that can not escape out, the adhesive material 140 'swells up and the lens barrel 110 The focus of the lens array 120 mounted on the lens barrel 110 may be disturbed and the resolving power of the camera module 100 may deteriorate.

The first adhesive member 140-1 of FIG. 8 has an opening 501 through which gas generated during thermal curing or UV curing of the adhesive material 140 'can escape.

Since the gas generated during the thermal curing or UV curing passes out through the opening of the first adhesive member 140-1, the embodiment can reduce the focal point of the lens array 120 by the gas generated during the curing of the adhesive material And it is possible to prevent deterioration of the resolving power.
