Abstract
A light-receptive module according to the present invention includes a board, a light-receptive element disposed with a light input face thereof facing toward the surface of the board, and an optical fiber disposed in a slot formed on the surface of the board and coupled with the light-receptive element. The optical fiber has an end face formed obliquely to the surface of the board so that light is emitted toward a light receive face thereof. The end of the slot has a recession formed in parallel with the surface of the board so that it contacts partially with the end face. The end face is formed at a total internal reflection angle so that light emitted from the optical fiber is subjected to total internal reflection. On the board is formed a slot in which the optical fiber is disposed. The optical fiber is secured to the slot in such a way that the end is thrust into a recession formed in the end of the slot.
