PROBLEM TO BE SOLVED: To provide an optical module capable of increasing an information transmission amount and achieving miniaturization, and to provide a cable with the module. SOLUTION: The optical module 1 is assembled at the end portion of an photoelectric composite cable 4 including an optical transmission path 2 and an electric wire 3. The optical module 1 includes: a circuit board 8; a photoelectric conversion part 9 connected to the circuit board 8; and an electric connector 5 which can be connected to another device. The electric wire 3 can be electrically connected to the electric connector 5 through circuit wiring when connected to the circuit board 8. The optical transmission path 2 includes an optical axis crossing the optical axis of the photoelectric conversion part 9 with a predetermined angle, and the path 2 is optically connected to the photoelectric conversion part 9 through an optical coupling part 13. The optical coupling part 13 is made of a transparent resin, and tightly adhered to the light receiving/emitting part of the photoelectric conversion part 9 and the end portion of the optical transmission path 2, respectively. The outer resin surface of the optical coupling part 13 is recessed toward the light receiving/emitting part of the photoelectric conversion part 9 and toward the end portion of the light transmission path 2.
