Abstract
An optical module comprising: an optical semiconductor element, an optical fiber optically coupled to the optical semiconductor element, a substrate on which the optical semiconductor element and optical fiber are mounted, and a sealing section wherein the optical semiconductor element and the region of the optical fiber containing the end face thereof adjacent to the optical semiconductor element are covered by a sealant. A sealant retaining section is formed in the substrate. The sealing section has a dome shape formed by a single layer of sealant, and the end portions of this sealing section, apart from the side thereof adjacent to the optical fiber, are fixed by a sealant retaining section. According to this composition, the optical fiber, optical semiconductor element and the optical coupling section between the optical fiber and the optical semiconductor element are sealed satisfactorily.
