Abstract
A method for producing a ferrule having a plurality of fiber holes for insertion of optical fibers formed between two pin holes for insertion of guide pins, and a ferrule produced by the method. The method comprises a step of injecting a synthetic resin in a mold for forming the ferrule while holding a plurality of pins with a Young's modulus of(22 to 59)×1010N/m2 for forming the fiber holes at two points separated by a distance of 1.5 to 4 mm in a lengthwise direction of the pins.
