Abstract: The lens tube includes a cylindrical barrel, a holder, a cap, and a stress applying portion. The barrel houses at least one first lens. The holder houses an imaging element and is fixed to a substrate. The holder is configured to allow one end of the barrel in an axial direction to be screwed into the holder such that an optical axis of the first lens and an optical axis of the imaging element are aligned with each other. The cap is mountable to the barrel by allowing the other end of the barrel in the axial direction to be screwed into the cap. The stress applying portion is located between the holder and the cap when the barrel is screwed into the holder and the cap, and applies a stress in a direction in which the cap is separated from the holder. The first lens is held and fixed between a first stopper formed on the cap and a second stopper formed in the barrel when the cap is mounted to the barrel.

Abstract: A focus adjustment method for a camera module equipped with an optical system, an image sensor, and a camera substrate to which said image sensor is mounted. The focus adjustment method includes a measurement step of measuring an installation position and an installation angle of the image sensor on the camera substrate, an adjustment step of adjusting a position and an angle of the camera substrate relative to the optical system, and an assembly step of assembling the camera substrate to the optical system after adjusting the position and angle of the camera substrate. The adjustment step includes adjusting the position and angle of the camera substrate based on the installation position and angle of the image sensor as measured so that a position and an angle of the image sensor relative to the optical system become a set position and a set angle predefined according to the optical system.

Abstract: A focusing adjustment method of a camera module predicts, before completion of securing of a camera board to an optical system, a shrinkage deviation amount by which the optical system and the camera board will approach one another. The focusing adjustment method adjusts a position and an angle of the camera board to separate, by the predicted shrinkage deviation amount, the camera board from the optical system as compared with a focusing attitude of the image sensor with respect to the optical system where the optical system is in focus on the image sensor to accordingly offset the predicted shrinkage deviation amount.
