Abstract
Provided is a wholly aromatic liquid crystalline polyester resin having excellent heat resistance and formability. The wholly aromatic liquid crystalline polyester resin comprises structural units represented by the following formulae (I) to (V) as essential structural units, wherein the composition ratio (mol %) of the structural units (I) to (V) in the wholly aromatic liquid crystalline polyester satisfies the following conditions: 50 mol %≤structural unit (I)≤75 mol %; 6 mol %≤structural unit (II)≤20 mol %; 1 mol %≤structural unit (III)≤21.5 mol %; 0.5 mol %≤structural unit (IV)≤10.5 mol %; 2.5 mol %≤structural unit (V)≤22 mol %; structural unit (III)>structural unit (IV).
