An optical pickup lens holder which comprises a wholly aromatic liquid crystalline polyester resin composition comprising 97 to 45 mass percent of a wholly aromatic liquid crystalline polyester having a melting point of 320° C. or higher, 3 to 50 mass percent of an inorganic spherical hollow material having an aspect ratio of 2 or less and 0 to 30 mass percent of an inorganic filler having as aspect ratio of 4 or more, wherein the percentages are made to 100 mass percent in total, and having a specific gravity in the range of 1.00 to 1.35. The lens holder exhibits excellent characteristics, while retaining good heat resistance in soldering and good processability inherent in a liquid crystalline polyester, exhibits high injection processability and high adaptability to a soldering process even in a sheet form lens holder having a thin part and an opening port.
