| description | PROBLEM TO BE SOLVED: To provide an optical filter having a near-infrared absorbing layer using a transparent resin having a fluorene skeleton on a glass substrate, in which adhesiveness between the glass substrate and the near-infrared absorbing layer is firm, and in particular, the optical filter has high reliability even when used in a high temperature and high humidity environment and secures a production yield, and to provide a solid-state imaging device having high reliability, which includes the optical filter.SOLUTION: The optical filter includes a glass substrate and a near-infrared absorbing layer formed on one principal surface of the glass substrate. The near-infrared absorbing layer is obtained by allowing a composition for forming the near-infrared absorbing layer to react on the glass substrate. The composition for forming the near-infrared absorbing layer comprises: a transparent resin having a reactive group and a fluorene skeleton; a near-infrared absorbing dye; and a silane coupling agent and/or oligomer thereof having a hydrolyzable group and a functional group reactive with the above reactive group. |
