Abstract
An optical module includes an optical waveguide including a plurality of waveguide cores through which light propagates, a clad configured to trap the light in the waveguide cores, a plurality of fiber guide grooves in which optical fibers are inserted, the fiber guide grooves being arranged in parallel, and an adhesive spread groove configured to connect the fiber guide grooves and provided at leading ends of the fiber guide grooves with which the optical fibers contact; and a fixing member fixed to the optical waveguide with an adhesive while covering the fiber guide grooves. The fiber guide grooves have side walls including support projections configured to support, align, and optical couple the optical fibers to the waveguide cores, and adhesive recesses configured to define gaps between outer peripheral surfaces of the optical fibers and the fiber guide grooves so that the adhesive spreads in the gaps.
