Abstract
The present invention provides a liquid crystalline polyester resin composition suitable for an optical pickup unit. The composition comprises a liquid crystalline polyester, a mica and a hollow filler. Using the liquid crystalline polyester resin composition, an optical pickup unit with a high soldering resistance and a high torsional elastic modulus can be produced while suppressing breakage of the hollow filler in the composition.
