<P>PROBLEM TO BE SOLVED: To provide a planar connector made of a liquid crystalline polymer having excellent crack resistance such that splitting does not occur in the lattice section after molding. <P>SOLUTION: The planar connector comprises: (A) a fully-aromatic polyester which comprises respective specific amounts of a structural unit I introduced from 4-hydroxybenzoic acid, that unit II from 6-hydroxy-2-naphthoic acid, that unit III from 1,4-phenylenedicarboxylic acid, that unit IV from 1,3-phenylenedicarboxylic acid and that unit V from 4,4'-dihydroxybiphenyl and which exhibits an optical anisotropy when melting; (B) a platy inorganic filler; and (C) a glass fiber. The connector is formed from a composite resin composition in which the components (B) and (C) are 15-25 wt.% and 10-25 wt.%, respectively, and the sum of components (B) and (C) is 30-40 wt.% based on the whole composition. The connector has a lattice structure inside an outer frame, and the pitch interval of a lattice section is 1.5 mm or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
