Abstract
An optical module includes a substrate, an optical element, an optical coupling module, and an adhesive. The substrate includes a glass cloth therein. The optical element is mounted on the substrate. The optical coupling module is configured to be optically coupled to the optical element. The adhesive fixes the optical coupling module to the substrate. A cavity recessed from a first main surface of the substrate toward a second main surface of the substrate so as to include a bottom portion is formed in the substrate. At least a part of the optical coupling module is accommodated in the cavity. The glass cloth includes a protruding portion protruding into the cavity from a side surface of the cavity. The protruding portion is stuck into the adhesive positioned between the side surface and the optical coupling module.
