<P>PROBLEM TO BE SOLVED: To provide a light receiving module for condensing the rays of light on a light receiving part with high efficiency even when the magnification of an optical system has a variation due to a variation in a distance between a light receiving part and a lens or a variation in the interval of cores of a multiple core ferrule. <P>SOLUTION: A light receiving module includes a lens 4 arranged between a plurality of emitting parts 6a and a plurality of light receiving parts 6b for condensing a plurality of incident rays of light 1 emitted from each of the plurality of emitting parts 6a to each of the plurality of light receiving parts 6b. The interval of condensation spots to be condensed to each of the plurality of light receiving parts 6b changes in accordance with an interval between each of the plurality of light receiving parts 6b and the lens 4, and the shape of each of the plurality of light receiving parts 6b is a track shape with a direction extended along a straight line which connects a central point 11 corresponding to a central axis of the lens 4 with the middle point of each light receiving part 6b as a longitudinal direction and with a direction which is vertical to the longitudinal direction as a transverse direction, and the plurality of light receiving parts 6b are arrayed in one axial direction with the central point as a center. <P>COPYRIGHT: (C)2013,JPO&INPIT |
