Abstract
A liquid crystal polyester resin composition includes a liquid crystal polyester (A) including repeating units represented by formulae (I) to (III), a liquid crystal polyester (B) including repeating units represented by formulae (IV) and (V), and surface-treated glass fibers (C) including an epoxy resin on the surface thereof, wherein the mass ratio of (A) to (B) [A/B] is from 90/10 to 45/55, the content of (C) is from 10 to 130 parts by mass relative to 100 parts by mass of the total amount of (A) and (B), and as measured in a bending test using a strip-like molded article (length: 127 mm, width: 12.7 mm, thickness: 0.5 mm), the bending strength and the bending elastic modulus of the liquid crystal polyester resin composition are equal to or more than 330 MPa and equal to or more than 20 GPa, respectively.
