Summary:To provide an invention in the field of optical lenses, in particular, a lens module.SOLUTION: A lens module provided herein comprises a lens barrel, a first lens disposed on the object side of the lens barrel, and a fixing member for pressing and holding the first lens against the lens barrel from the object side of the first lens. The fixing member has a top wall for pressing and holding the first lens, and a side wall bending from the top wall and extending toward the image side to be fixedly coupled to the lens barrel. Colloid is filled between the side wall and the first lens to allow the first lens to be bonded and fixed to the side wall by the colloid. The lens module of the present invention offers high reliability and superior sealing performance.SELECTED DRAWING: Figure 1 【課題】本発明は光学レンズ分野に関し、レンズモジュールを提供する。【解決手段】レンズモジュールは、鏡筒と、前記鏡筒の物体側に設けられる第１レンズと、前記第１レンズの物体側前記第１レンズを前記鏡筒に押圧保持する固定部材とを備え、前記固定部材は、前記第１レンズを押圧保持する頂壁と、前記頂壁から像側へ屈曲して延在し、前記鏡筒に固定接続される側壁とを備え、前記頂壁は、前記第１レンズに接し、前記側壁と前記第１レンズとの間にコロイドが充填され、前記コロイドによって前記第１レンズが前記側壁に接着固定されている。本発明に係るレンズモジュールは、信頼性が高く、密封性能が良い。【選択図】図１
