The present invention relates to a camera module, which comprises a packaged image sensor, an IR filter, a lens and a holder for holding these components and has a reduced overall size and height. A camera module according to the present invention comprises an image sensor package having a translucent substrate formed thereon; and a holder having a lower end attached to the translucent substrate of the image sensor package. At this time, the holder comprises a horizontal portion formed with a through-hole and a connecting portion extending downwardly from an edge of the horizontal portion, and an end surface of a lower end of the connecting portion is formed with an inner stepped portion so as to be attached to a peripheral portion of a top surface and a lateral surface of the translucent substrate. Alternatively, the holder comprises a horizontal portion formed with a through-hole and a connecting portion extending downwardly from an edge of the horizontal portion, and an end surface of a lower end of the horizontal portion is formed to be flat such that it is attached to a peripheral portion of a top surface of the translucent substrate. Otherwise, the holder comprises a horizontal portion formed with a through-hole, and a bottom surface of the horizontal portion is attached to at least a peripheral portion of a top surface of the translucent substrate.
