Patent ID: 7542647

Claim:
An optical reception and transmission module comprising: an optical waveguide film formed with an optical waveguide; an optical transmission unit having a light emitting device and a first holding member for holding the light emitting device, and which holds a first end portion of the optical waveguide film on the first holding member so that light emitted from the light emitting device is coupled to an incident end surface of the optical waveguide; and an optical reception unit comprising a light receiving device and a second holding member for holding the light receiving device, and which holds a second end portion of the optical waveguide film on the second holding member so that light emitted from an emitting end surface of the optical waveguide is received by the light receiving device, wherein at least the optical waveguide film is covered with flame-retardant resin having flame retardancy of HB or higher according to a UL-94 test and a minimum bending radius of the optical waveguide film covered with the flame-retardant resin and having a flame-retardant resin layer formed on a surface thereof is from 1 mm to 3 mm.
