PURPOSE:To facilitate optical axis alignment and to reduce the size of the IC socket by integrating and connecting electrically a transmitting and receiving element structure for information transmission by an optical fiber and a socket where an IC is inserted and fixed. CONSTITUTION:The IC with the optical connector is constituted by incorporating the optical fiber receiving structure consisting of a light receiving element 2, a condenser lens 3, and the optical fiber socket 4 which facilitates the attachment and detachment of the optical fiber in the IC socket 5 as an optical connector 6. The light receiving element 1 uses, for example, an Si photodiode and is in a chip or individual component shape and mounted on the bottom part of an optical connector part 6. The light emitting element 2 uses, for example, a GaAs light emitting diode, etc., and is in a chip or individual component shape and mounted on the bottom part of the optical connector part 6 adjacently to the light receiving element 1. The light receiving element 1 and light emitting element 2 are formed preferably on the same substrate nearby each other and light mixture from the light incidence from the light emitting element 2 to the light receiving element 1 is prevented properly by boring a window or using resin, etc.
