To provide a fabricating method of an optical communication part in which an optical element is fixed within a hollow holder, including the step of fixing an optical element by holding the optical element in a hollow portion of a holding portion of a metal made holder and calking a portion of the holder; wherein, the step includes calking the holder by heating the holder to a temperature higher than a operating temperature or cooling the holder to a temperature lower than the operating temperature depending on whether or not a thermal expansion coefficient of the holder is larger or smaller than that of the optical element. When the thermal expansion coefficient of the holder is larger than that of the optical element, and a heating temperature in calking is set within the range of 85° C. to 95° C., while when the thermal expansion coefficient of the holder is larger than that of the optical element the cooling temperature of the holder upon the calking is set within the range of -50° C. to -40° C.
