ABSTRACT:
In the jointing method of jointing an optical fiber F a softening point of which is higher than an optical lens L to the optical lens L, only the optical lens is softened by heating, and an end face as a joint portion of the optical fiber is pushed into a joint portion of the softened optical lens to thereby joint them.
