Abstract:
A powdery liquid-crystal resin for a press-molded article is disclosed having a bulk density of more than 0.05 g/cm3 and 0.5 g/cm3 or less. The powdery liquid-crystal resin preferably has a particle diameter distribution width as defined by JIS Z8825: 2013 of 3.0 or more and 12 or less. The powdery liquid-crystal resin preferably has an average particle diameter of 10 μm or more and 300 μm or less. The degree of crystallinity of the powdery liquid-crystal resin is preferably 20% or more and 70% or less.
