IPC: H01L31/173
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To make light transmission efficiency high and stable between a light emitting and receiving elements. SOLUTION: A transmissive resin protruding portion 16 has a constant height within the range from a light emitting element 13 to a light receiving element 14, and its sectional shape is made triangular. Further, since the outer package 17 is white, interfaces between the transmissive protruding portion 16 and the outer package 17 are made white to make high the optical reflection factors of the interfaces. From these facts, the emitted light from the light emitting element 13 so reaches the light receiving element 14 while it is reflected and constricted by respective surfaces 16a, 16b of the transmissive resin protruding portion 16 as to be received by the light receiving element 14.  In this case, since the light is transmitted in the transmissive resin protruding portion 16 from the light emitting element 13 to the light receiving element 14 without dispersion and since its transmission distance is short, the transmission efficiency is made high and stable.
