Since the blocking member 1500 is disposed so that at least a portion of the blocking member 1500 overlaps the terminal 1830 and/or the wire 1840 in the optical axis direction, among the light 1010 passing through the lens or the lens barrel 400, the light 1010 passes through the circuit board 800. Light directed to the terminal 1830 or/and the wire 1840 may be blocked to prevent the above-described flare phenomenon from occurring, and accordingly, an image formed on the image sensor 810 may be prevented from being distorted or degraded. can

The side surface 61 of the filter 610 may be spaced apart from each of the first surface 601 and the second surface 602 of the inner surface 511 of the mounting portion 500 .

An area of the bottom portion 512 of the holder 600 corresponding to the space between the side surface 61 of the filter 610 and the second surface 602 of the holder 600 is the holder 600 holding the filter 610.

For example, the ratio (D1:D2) of D1 and D2 may be 1:2.8 to 1:8.

When the value obtained by dividing D2 by D1 (D2/D1) is less than 2.8, the separation distance between the filter 610 and the first surface 601 may become too small, and as a result, the first surface 601 and A collision between the filters 610 may occur.

Also, when the value (D2/D1) obtained by dividing D2 by D1 is greater than 8, the size of the holder 600 may increase, thereby increasing the size of the camera module according to the embodiment.

When the height H1 is lower than the central point CP of the side of the filter 610, when the filter 610 is seated or placed on the seating part 500, the filter 610 is placed on the upper surface of the protruding part 65. It can go up, and due to this, misalignment of the arrangement of the filter 610 may occur.

In addition, when the height H1 is greater than the thickness of the filter 610, the upper surface of the protruding portion 65 may be located higher than the upper surface of the filter 610, and thus the protruding portion 65 and the filter 610 may be affected by external impact. ) may occur, and cracks may occur in the filter 610.

The thickness T1 of the filter 610 is the distance D2 from the first side 601 of the holder 600 to the side 61 of the filter 610 and the second side 602 of the holder 6000. It may be greater than or equal to the length d11 obtained by subtracting the separation distance D1 from the side surface 61 of the filter 610 (T1 > d11).

In addition, d11 may correspond to the length of the protrusion 65 of the holder 600 in the direction from the first surface 601 of the holder 600 to the side surface 61 of the filter 610 .

The protruding part 65 may come into contact with the lower end of the inner surface 511 of the seating part 500 and the bottom surface 512 of the seating part 500 . In another embodiment, the protruding portion may be disposed on the inner surface 511 of the seating portion 500 and may be spaced apart from the bottom surface 512 of the seating portion 500 .

The interface unit 770 receives data from an external device or receives power and transmits it to each component inside the terminal 200A, or transmits data inside the terminal 200A to an external device. For example, the interface unit 770 may include a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port connecting a device having an identification module, an audio I/O (Input/ Output) port, video I/O (Input/Output) port, and earphone port.

The controller 780 may control overall operations of the terminal 200A. For example, the controller 780 may perform related control and processing for voice calls, data communications, video calls, and the like.

The controller 780 may include a multimedia module 781 for playing multimedia. The multimedia module 781 may be implemented within the control unit 180 or may be implemented separately from the control unit 780.

The controller 780 may perform a pattern recognition process capable of recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

The power supply unit 790 may receive external power or internal power under the control of the control unit 780 to supply power necessary for the operation of each component.
