ABSTRACT:
The present invention provides a connecting member for facilitating connecting of optical fibers, and a connecting method in which the loss due to connecting is small. An optical fiber connecting member is composed of: a retaining portion having through-holes each of which has an inner diameter slightly larger than the outer diameter of optical fibers to be connected; and introduction portions which are integrally formed with and on the opposite end sides of the retaining portion and each of which has introduction grooves communicated with the through-holes to thereby make it easy to insert ends of the optical fibers into the through-holes. Further, the inner diameter of each of the through-holes is reduced by heating the connecting member to thereby make axis alignment of the optical fibers automatically to obtain connecting in which the connecting loss is reduced.
