Abstract
An optical module includes a substrate, an optical element, and an optical coupling module. The substrate includes a glass cloth constituted of glass threads serving as weft and warp. An outer edge of the substrate has a rectangular shape defined by a pair of first side surfaces in a predetermined direction and a pair of second side surfaces in a direction orthogonal to the predetermined direction. The weft is inclined with respect to the first side surfaces and the second side surfaces. The warp is inclined with respect to the first side surfaces and the second side surfaces. A cavity is formed in the substrate. At least a part of the optical coupling module is accommodated in the cavity. A side surface of the cavity includes an inclined region inclined with respect to an extension direction of the weft and an extension direction of the warp.
