Abstract
An optoelectronic module, including a substrate, a covering member, a light emitting element, and a light receiving element, is provided. The covering member is disposed on the substrate and includes an upper cover portion, a peripheral sidewall portion connected to the upper cover portion, and an inside partition delimiting a first cavity and a second cavity. The first cavity is separated from the second cavity. The light emitting element is disposed on the substrate as corresponding to the first cavity. The light receiving element is disposed on the substrate as corresponding to the second cavity. The inside partition has a first inner wall surface located in the first cavity and a second inner wall surface located in the second cavity. A first protruded-recessed structure is formed on the first inner wall surface.
