PROBLEM TO BE SOLVED: To provide an optical semiconductor device of high reliability wherein a translucent lid and an insulating substrate are joined firmly, hermeticity of a sealing volume which contains an optical semiconductor element is superior, normal light receiving of outdoor daylight by the optical semiconductor element is enabled without generating distortion over long period of time, and normal electric signals are sent to external devices or elements. SOLUTION: The optical semiconductor device 9 is constituted of: the insulating substrate 1 which has a recess 1a for accommodating the optical semiconductor element 3 on an upper surface; a wiring conductor 2 led out from interior of the recess 1a of the insulating substrate 1 to the outside; the optical semiconductor element 3 which is bonded to the bottom surface of the recess 1a of the insulating substrate 1 and in which an electrode is electrically connected to the wiring conductor 2; and a translucent lid 5 which is joined to the upper surface of the insulating substrate 1 through bonding material 7 so as to close the recess 1a. The translucent lid 5 is provided with grooves 5a around the entire circumference at the central part in the direction of thickness of its side surface, and a part of the bonding material 7 is inserted in the grooves 5a.
