    Abstract: Provided are a hybrid optical coupling module and a manufacturing method thereof.The hybrid optical coupling module includes an optical unit configured to include an optical transmission means that transmits an optical signal, and an array lens that is bonded at a point where the optical signal of the optical transmission means is output and focuses the output optical signal, and an electrical unit configured to receive the optical signal focused through the array lens and convert the received optical signal into an electrical signal. Here, an alignment mark is formed on the optical transmission means and the array lens so that the array lens is bonded at the point where the optical signal of the optical transmission means is output.
