| 1. A method of producing an optical transmission component comprising the steps of:
performing integral resin molding while at least a part of an optical transmission line holder and an optical function portion
are connected by a connection portion, the optical transmission line holder and the optical function portion being disposed
with a space;
holding the optical transmission line in the optical transmission line holder while an end face of the optical transmission
line is located across the space from the optical function portion;
filling a gap portion between the optical function portion and the end face of the optical transmission line with a bonding
agent having a linear expansion coefficient smaller than that of the connection portion; and
curing the bonding agent at an atmosphere temperature higher than an upper limit of a keeping temperature of the optical transmission
component.
