Abstract
The present invention provides an optical module capable of reducing the amount of electrostatic charges on a shielding member. The optical module comprises an assembly portion and a shielding member. The assembly portion includes a light receiving device, an electronic element, a circuit board, and a plurality of terminals. The light receiving device includes a semiconductor optical element. The semiconductor optical element is optically coupled to an optical connector. The electronic element is electrically connected to the semiconductor optical element. The circuit board mounts the electronic element thereon. The plurality of terminals is electrically connected to the circuit board. The shielding member includes a reference terminal provided so as to be connected to a reference potential line, and shields the assembly portion. In this optical module, the assembly portion is provided with an electrically conductive piece provided so as to connect the shielding member to at least one of the plurality of terminals.
