An optical module including a substrate, an optical waveguide formed on the substrate, and an optical element mounted on the substrate so as to be optically coupled to an end of the optical waveguide, for performing conversion between light and electricity. The optical module further includes a transparent resin for covering at least an optical coupling portion between the optical waveguide and the optical element, and a thermoplastic resin for covering only the optical element and its periphery including the transparent resin to seal the optical element.
