Kind Code:
B2
Abstract:
To provide a liquid crystal polyester molding including an ultrathin wall part, of a member constituting a product, having higher bending strength, and a connector using the same.SOLUTION: In the liquid crystal polyester molding, the crystallite size of a molding central portion calculated from a crystallite size determined by a crystallite size measurement method is 120×10-10 m or more. The crystallite size of the liquid crystal polyester molding by the crystallite size measurement method is calculated by the Scherrer formula represented by the formula (1) on the basis of 110 plane diffraction peaks in an X-ray diffraction spectrum measured by a wide angle X-ray diffraction method using an X ray having a wavelength of 1×10-10 m. D=Kλ/βcosθ ... (1), where D is a crystallite size; λ is a measurement X ray wavelength; β is a half value width(radian), θ is a diffraction angle; and K is a Scherrer constant (0.94).SELECTED DRAWING: None
