Abstract
An optical ferrule is a molding of a resin composition comprising a base resin, silica, and whisker, as essential components. The resin composition has a melt viscosity of 300 to 600 [Pa×sec.] when measured at a shear rate of 900 [1/sec.] at a temperature of 340° C. by using a capillary having a diameter of 0.1 mm and a depth of 30 mm as defined by JIS-K-7199. Preferably, the base resin is a linear polyphenylene sulfide resin, and 250 to 300 parts by weight of silica and 10 to 70 parts by weight of whisker are blended with 100 parts by weight of the linear polyphenylene sulfide resin.
