<P>PROBLEM TO BE SOLVED: To provide an optical signal transmission apparatus capable of preventing signal deterioration by suppressing the deviation of the intensity distribution of transmitted light. <P>SOLUTION: The optical signal transmission apparatus, for transmitting a signal by using light, comprises: a light emitting means for emitting light; an optical transmission line surrounded with a reflection plane reflecting light from the light emitting means; a photoconductor having an emission end from which light transmitted by the optical transmission line is emitted; and a light receiving means for receiving light emitted from the photoconductor. The photoconductor has a first transmission part formed so as to reduce a distance between an optical axis of the photoconductor and the reflection plane toward the emission end, thereby suppressing the deviation of the intensity distribution of light transmitted via the photoconductor. <P>COPYRIGHT: (C)2010,JPO&INPIT |
