A lens barrel for holding a lens includes a barrel body for containing the lens. A ring shaped receiving wall is formed on the barrel body, for receiving a rear face of a peripheral portion of the lens, to position the lens in an optical axis direction. Three retaining claw portions are disposed to project from the barrel body, for retaining the lens on the ring shaped receiving wall by engagement with the peripheral portion thereof. Three first through holes are formed in the barrel body, and adapted to insertion and pressure of an external adjusting rod for positioning adjustment of the lens. Second through holes are formed in the barrel body, and adapted to introduction of adhesive agent for attaching the lens on the barrel body. The retaining claw portions and the first through holes are arranged at a regular pitch on a circumference of the barrel body.
