An optical module includes a substrate, one or a plurality of planar optical devices mounted on the substrate, and a waveguide block including one or a plurality of curved waveguides formed on a plane. The waveguide block is mounted on the substrate such that the plane on which the curved waveguides are formed is perpendicular to the substrate and the curved waveguides and an incidence face or an emitting face of the planar optical device are opposed to each other on one end face of the waveguide block. Further, the waveguide block is configured so that an optical fiber can be connected to the other end face of the waveguide block which is orthogonal to the one end face.
