摘要： A camera module includes a carrier, disposed in an internal space of a housing, configured to receive a lens barrel, and having an external rolling portion corresponding to the internal rolling portion on an exterior side; a focus adjustment driver configured to generate a driving force to move the carrier in an optical-axis direction in the housing; and a rolling member disposed between the internal rolling portion and the external rolling portion. Either one or both of the internal rolling portion and the external rolling portion includes a guide groove, formed on an external surface of a mold forming an exterior of the housing or the carrier, including a pair of rolling sides facing each other with a predetermined angle, and a reinforcing insert made of a material having greater strength than a material of the mold.
