Beschreibung
Zusammenfassung:	An optical device assembled by means of an adhesive composition which is free from the cracking of an adhesive layer thereof, is prepared easily and has excellent adhesive strength. The optical device is produced by placing an adhesive composition prepared by hydrolyzing, dehydrating and condensing a starting solution which contains 10 to 50 mol% of a silane compound represented by SiX 4 (X is a hydrolyzable group) or a combination of the silane compound and a metal alkoxide, 25 to 65 mol% of a silane compound represented by PhSiX 3 (Ph is a phenyl group or substituted phenyl group, and X is a hydrolyzable group), and 25 to 65 mol% of a silane compound represented by (CH3)2SiX 2 (X is a hydrolyzable group) between an optical part and another part and heating it to bond the optical part to the another part.
