The lens barrel member includes: a lens barrel surrounding an outer periphery of a lens; and a housing receiving the lens barrel, the lens barrel being secured to the housing, wherein the lens barrel is formed of a lens barrel composition including: about 50 wt % to about 75 wt % of a polycarbonate resin; about 20 wt % to about 45 wt % of a glass fiber; about 0.5 wt % to about 3 wt % of a polyolefin wax; and about 0.5 wt % to about 3 wt % of a fluorinated olefin resin, and a weight ratio of the polyolefin wax to the fluorinated olefin resin ranges from about 1:0.3 to about 1:3. The lens barrel member can have a low coefficient of friction and/or good properties in terms of rigidity and/or dimensional stability.
