<P>PROBLEM TO BE SOLVED: To promote small size various optical communication equipment etc., mounted with an optical device by reducing the size and thickness of the optical device. <P>SOLUTION: The optical device 10 has a base 12, an optical component 14 which is mounted on the base 12 and has at least one element, and a transparent gap member 16 which is fixed onto the base 12 to cover the optical component 14 and is a single body and transparent. Then the angle θ between the bottom 22a and side wall 22b of a recessed portion 22 is ≤90° and and the boundary 22c between the bottom 22a and side wall 22b of the recessed portion 22 is curved. Further, the depth (h) of the recessed portion 22 is ≤1.0 mm. <P>COPYRIGHT: (C)2007,JPO&INPIT |
