Summary:PROBLEM TO BE SOLVED: To provide a camera module capable of minimizing power consumption and a tilt phenomenon of a lens barrel by removing a preload part, improving reliability of drive, and reducing self-vibration during drive of the lens barrel by bonding a damping member.SOLUTION: A camera module comprises: a lens barrel 110 incorporating a lens; a housing 120 with an accommodation space accommodating the lens barrel 110; a drive part 130 composed of a magnet 132 and a coil 134 and configured to provide first driving force for driving the lens barrel 110 upward by electromagnetic force generated by the magnet 132 and the coil 134, and second driving force for driving the lens barrel 110 downward; a guide ball 140 provided between the lens barrel 110 and the housing 120 and configured to guide movement of the lens barrel 110; and a position detecting part 150 configured to detect a position of the lens barrel 110. The drive part 130 drives the lens barrel 110 upward and downward. 【課題】プレロード部をとり除いて電力消耗及びレンズバレルのチルト現象を最小化し、駆動の信頼性を向上させることができ、ダンピング部材の結合により、レンズバレル駆動時の自体振動を軽減させることができるカメラモジュールを提供する。【解決手段】レンズが内蔵されたレンズバレル110、レンズバレル110が収容される収容空間を備えるハウジング120、マグネット132とコイル134で構成され、マグネット132とコイル134から発生する電磁気力により、レンズバレル110を上方に駆動させる第1駆動力と、レンズバレル110を下方に駆動させる第2駆動力を提供する駆動部130、レンズバレル110とハウジング120の間に備えられてレンズバレル110の動きを案内するガイドボール140、及びレンズバレル110の位置を検知する位置検出部150を含むことを特徴とし、駆動部130がレンズバレル110を上下に駆動させる。【選択図】図4
