<P>PROBLEM TO BE SOLVED: To implement a high image quality optical device whose transparent member is less likely to be tilted. Ž<P>SOLUTION: The optical device includes a substrate 11, a plurality of optical elements 13 formed in an element formation region 12 of the substrate 11, a plurality of lenses 15 formed over the element formation region 12 so as to correspond to the plurality of optical elements 12, and a protective layer 17 formed so as to cover the plurality of lenses 15. A holding member 19 is formed on a region outside the element formation region 12 in the protective layer 17, and the holding member 19 holds a bottom surface of a transparent member 21. A gap between the protective layer 17 and the transparent member 21 is filled with an adhesive 23. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
