An optical connector includes a circuit board. The circuit board includes a substrate and a circuit unit. A photoelectric element and a driver chip are located on the substrate. The photoelectric element includes a conductive pin and a metallic layer. The conductive pin is formed on a surface of the photoelectric element away from the circuit board, and the metallic layer is formed on another surface of the photoelectric element facing the circuit board. The conductive pin and the metallic layer serve as terminals of the photoelectric element. The driver chip is electrically connected to the photoelectric element by the circuit unit.
