A photoelectric device includes a ceramic substrate defining a cavity in a top thereof and having two electrode layers beside the cavity. A photoelectric die is received in the cavity. A first packing layer is received in the cavity and encapsulates the photoelectric die. The photoelectric die is electrically connected with the electrode layers via two wires. A reflective cup is mounted on the ceramic substrate and defines a receiving space above the top of the ceramic substrate and the first packing layer. A second packing layer is received in the receiving space and covers the first packing layer.
